NS-3 is a complex tool that runs simulations described by code created by users, so you may need programming skills to use it. NS-3 can run real software on simulated nodes using its Direct Code Execution feature. This allows researchers to test real software like Quagga or web servers in a discreet-event network simulation to produce repeatable experiments. NS-3 is meant to replace NS-2 , a previous version of the network simulator.

NS-2 is no longer actively maintained but is still used by some researchers. Users run a simulation by creating an XML file to describe the network topology and plugins to link their application code to nodes in the simulation. They see the results of their experiments in log files generated by Shadow. Shadow operates as a discrete-event simulator so experimental results are repeatable. Shadow can also run real software on its virtual nodes, using plugins created by the user.

This combination of features — discreet-event simulation coupled with real software emulation — makes Shadow a unique tool. I have not yet used Shadow. It seems to be useful to developers who want to test the performance of distributed or peer-to-peer applications like TOR and Bitcoin.

VNX supports two different virtualization techniques and uses an XML-style scripting language to define the virtual network. It also supports chaining multiple physical workstations together to support distributed virtual labs that operate across multiple physical workstations.

It is supported by a small community and has been updated within the past year. Software developers and network engineers use vrnetlab, along with continuous-integration processes, for testing network provisioning changes in a virtual network. Researchers and engineers may also use the vrnetlab command line interface to create and modify network emulation labs in an interactive way. Please click here to see my posts about vrnetlab.

Wistar is an open-source network emulator originally developed by Juniper Networks and released under the Apache license. Wistar also supports Linux virtual machines and, interestingly, uses cloud-init to configure them from the Wistar user interface.

Wistar also supports generic virtual appliances, in a basic way. Please click here to see my posts about Wistar. Linux provides many different ways to build a network emulator using open-source virtualization technology and tools. Many of the network emulators described in this blog us some of the tools mentioned above to implement their functionality. Please click here to see my posts about building your own network emulator.

Containernet is a fork of the Mininet network emulator that allows you to use Docker containers as hosts in emulated network topologies. The Knet network emulator uses Docker containers to build network nodes, and it uses Open vSwitch to create switches. KNet has both a CLI and a web interface. The Educational Network Simulator is a very simple educational network simulator intended to be used with year old students.

Labtainers is a network emulator based on Docker containers that also provides many prepared labs that focus on cybersecurity scenarios. NetMirage is a network emulator developed at the University of Waterloo in Canada. It is currently available as an open beta. Similar to other network emulators, NetMirage allows users to run real code to test IP applications.

The NetMirage developers are currently using it to construct large-scale virtual Tor networks. Netsim is a network simulator framework for Rust programmers who need to test their networking code. See more details about YANS. There have been no updates in two years.

After releasing the first version, it has not been updated in two years. Marionnet allows users to define, configure and run complex computer networks on a host computer. Marionnet seems designed to be used as an education tool and has an attractive graphical user interface, and some sample practice lab configurations. The Marionnet project released a new version, 0. Psimulator2 is a Java-based network simulator useful for basic networking education. It is an old project, recently forked a couple of times by different developers so, hopefully, we will see some active development in the future.

It has not been updated in four years. LStacker is builds virtual networks consisting of containers and bridges. It supports both LXC and Docker containers. It was created three years ago but has not been updated since. I cannot wait for all the missing evaluations, this web site does exactly what I wanted to do but failed to find the time for it.

I am not even sure about my own vision of these word definitions emulation, and simulation , clearer definitions could be put on this web site. I wanted to find this site! Now I can see an emulator is really want I need. But sometimes you have to think about what the end user is going to search for. Based on what I know about all the tools in this list, I think that GNS3 is the only system that will work on Windows.

The instructor will have to do some work to create the system and simplify the desktop setup so that the complexities of using an unfamiliar operating system are hidden from the students but as soon as IMUNES or CORE is started, the students will be using the application and not worrying about running Unix BSD Unix commands. Is these emulator or simulation tool will help me to do my job??

If so, use GNS3 or Cloonix. If the system runs on top of Linux, you may be able to use containers so you could use CORE in that case. Thanks, Brian. Appreciate any suggestions or things to avoid. Thanks Maurice. This is a great article and information for people who are like me Developers by nature but still want to have a edge on the networking concepts.

I feel bad I have missed it for so long. Hi Vijay, Thanks for your interest in this blog. I have almost completed my survey of open-source network simulators so, over the next few months, I will begin discussing examples of simulated networking scenarios. I hope you and your team will find this blog to be useful. It also offers a useful selection of other Linux software and tools pre-installed. I have tested it. Without configuring anything, you can do the same things that with Cloonix or NetKit with VisualNetkit.

One of its advantages is that nothing is installed, modified or deleted on your own OS. I fixed my contact e-mail address. And, thanks for the extra information about Live Raizo. I think Live Raizo is a good project. They also make it easier to use GNS3 to build simulation scenarios.

Brian: You have a great resource here. Thanks for making all this info available. I want to connect openNMS to an emulator and then have the emulator run simple scenarios that present a network admin with various types of problems to diagnose and correct. Any suggestions would be most appreciated. Thanks Larry. Hi Larry, Thanks for your question. I think you should use a network emulator that runs either KVM or user-mode linux.

So use either Cloonix or Netkit. Brian: Thanks for the feedback. Thanks again Larry. Larry, Thanks. I think the main issue is virtualization of the file system. Cloonix and Netkit use KVM and user-mode-linux, respectively and those technologies virtualize the full filesystem and allow you to save the changes to the files for future use. Good point, David! GNS3 would also be a good tool for this case.

I have a few posts on using open-source routers in GNS3. Click on the GNS3 tag to find them. I had posted the same question on an openNMS forum and gotten zero responses so I really appreciate the info being provided here. I think for my needs the best fit will be something that is fairly broad in scope e.

The idea is to get a basic network emulation going and than interface to it via openNMS. My understanding is that Cloonix is pretty easy to set up and use, allows the use of standard Linux networking tools e. I prefer cloonix for working with open-source routers, in the case where full-stack virtualization is needed using KVM.

Both cloonix and GNS3 provide high-fidelity network simulation because they allow you to work with virtual machines running real networking software. Cloonix is more streamlined for use with open-source routers and other open-source software, which I think fits better with your use-case for working with OpenNMS. Hi Brian, Thanks for this great article. I test access multiplexers and would like to create a network of guest hosts, each with their own IP. The purpose of this is to try to congest multiplexer-under-test with TCP traffic.

There will be a simulated PC for each of the modems connected to a multiplexer-under-test that supports between modems. I would then like to set up a packet TCP generator or an FTP server on the uplink of the multiplexer, where the guest hosts would then simultaneously download files from the server. You need to do some testing to determine which options work best for you. In my opinion, you need a hypervisor like Xen, KVM, of VMWare or you can use Linux containers maybe use Docker , which use less systme resources than full VMs and may allow you to run more virtual test nodes per host machine.

Set up your VMs and connect them all to the 10G port. Even then, I would recommend other tools like chef or puppet or use shell scripts instead of a network simulator for your test system because it seems you will need more functionality related to virtual server setup automation instead of simulating different network topologies.

Thanks for quick reply, Brian. I mostly use python for automation scripting. Or do I use tools like Jmeter? You will have to do some testing, I think. You can create a set of virtual servers that all connect to the external Ethernet interface on the host machine. You can create a custom service type that supports starting an FTP client and then running some download commands.

When you save the network scenario, you can re-load it at a later date to run the same test again. Is there any free network simulator software that I can use as a tool to develop and demonstrate a working IPS within a simulation? Hi Adam, Thanks for your question. What protocols do you intend to use in your solution? If you can describe your needs in terms of the technology you need to emulate, you may be more successful in finding answers.

We are working on implementing communication network testbed for a smart grid system. Can you please recommend an emulation tool with realistic performance and which is not complicated to configure? I think your requirements exceed the capabilities that the open-source tools that I know about can provide.

I have working in research about detecting a malicious router that can attack autonomous system AS so I want to simulate simple AS with some routers and simulate a malicious router that drop the traffic maliciously I want to select the simulator to use it in this research , some ones advice me to use NS2 simulator.

I think you will want to run real software on virtual nodes in this scenario so I recommend you use a network emulator for your project. You should choose a network emulator that uses virtualization technology and scripting languages you are comfortable using. If you need a recommendation I can say that CORE and Cloonix are easy to use and should meet your requirement to run BGP routing software on different nodes in an emulated network.

But any of the other emulators except for Psimulator will also work for you. I am research student. I want make simulation about surveillance camera in WIMAX , can you help me which program can be effective and easy to use. Thanks for this overview.

I have not used it yet but it was recommended and seems to have won a few awards in A new beta is quite current. Cheers Christian. So, I did not list it among the set of open-source simulators on this page. Thanks for you post. This means that each node does not have its own filesystem upon which you can install apps.

You need to install applications on your host computer, like I do in my post about installing CORE services. Then, when you start a virtual node in the CORE Network Emulator, that node can run the app in a separate process namespace. Also you need to be aware of how CORE sets up configuration files in the filesystem for each service that runs, especially if you will create your own custom services.

Remember, you should not just start a process on a CORE node. I encountered the same problems I suspect you will encounter. We should be able to introduce heavy errors for retransmission such as packet drop, congestion, etc. Which of these will be a better fit?

Someone from work recommended ns Please help. Thank you Sean. Hi Sean, If you need results that are consistently reproducible, you should use a discreet-event network simulator like NS If you can accept some variability in measured performance then it is much easier to use a simulator like those listed on this page.

Thanks for this list of NS. It contribute and simplify the work of find a suitable tool for networking teaching. Best work. You will need to set up the packet core network functionality yourself, regardless of which simulation p,at form you use. I hope that helps. It is written in Python so you can modify it as you need to. You may also look at Mininet.

I hope your research is successful. I suggest that you look at the RouteFlow project for some inspiration. I am working on a student project and want to simulate some IP-based fast reroute techniques, can you recommend a simulator that can help me? I appreciate any advice you give me! Hi Jiadai, Fast-reroute techniques are implemented by the routers you emulate.

So the simulation tool you use is not a factor in making this work. I have read some papers about IP-based fast reroute techniques. So how I can make the simulation work to evaluate those mechanisms? I am still a newbie, hope you can give me some hints. ECMP is implemented in the Linux networking stack and it is probably one of the fast reroute technologies covered in the papers you read. Regards, Brian. I suggest you post your question to the Cloonix mailing list.

I am sorry to say that there has been a cloonix mailing list once, but now, the list is closed. There is very little communication around cloonix apart from this blog here. Do not hesitate, Brian to forward anything concerning cloonix to the cloonix team. The mail you transmitted about saving and configuration was good for the product progress, the needs we have here usin the tool is not the same as the needs other people may have.

Here we never save a topology, we just scritp its construction and send configuration commands to virtual machines always starting from virgin reference guests. Thanks Brian for this blog. Sorry about that, next version 29 will have the save function back. The rewriting and simplification of cloonix had side-effects.

This way you can test security with different distributions, kernels, and even with operations systems like Windows. Yes, i have used VirtualBox but not real scenario. In all except openwrt, you can install gcc, compile and run your patched software. You can also update your virtual machines at any time providing the host in which cloonix server is running has an internet connection. The next version of cloonix v29 will be available before chrismas. I think it depends on how you will set up your test scenario.

Will you be modifying the Linux kernel? Will you run modified networking stacks on some of the nodes on the network? If you need to run a lot of nodes in the simulating or will all use the same kernel and networking software, use a simulator based on containers, like CORE or Mininet. If you need performance accuracy and reproduceable measurements of performance, I suggest you use a discreet-event simulator like NS-2 or NS Hi Brian, I am working on M. I want to setup ipv6 bgp scenario and analyze route reflector and ibgp performance on heavy traffic loads.

Earlier,I have simulated ipv4 bgp in ns2 but now i am not able to scale it in ipv6. Please suggest. Hi Shipra, I need to know more about the simulation scenario you want to create. I assume that, since you are using NS-2, you need a discreet-event simulator so only NS-2 or NS-3 would work for you because they are the only discreet-event open-source network simulators I know about.

Since you wish to simulatate heavy workloads, I think a simulator like NS-2 or NS-3 is the best solution because using an emulator to run heavy workloads may not provide reproducible results. Is there any tool that i can use to simulate users, i. Hi Khawar, You could use most of these tools to create a network that has users with unique IP addresses. But what if I have one system that emulates the x number of users, obviously with different IP addresses, and one system containing my network or wan and other sections of the experiment?

I was wondering I have a named interface with a single IP address attached to it so my network other physical computers will be seeing it as a single user. Are these software able to work around that as well? CORE will do this. Of the simulators I have reviewed, I think Psimulator2 is the only one that would not work for you. Got the idea. Since you are online, I should put another question as well. Can this setup be used as an overlay to test another protocol that is similar to IPv6 or I would have to port the implementation into the simulator itself and then use that code to interact with IPv6 network.

One such scenario might be to test a protocol e. You need to install the software you will test so it will run on the virtual nodes. See my post about making custom services in CORE. It would be simpler to do this in Cloonix or GNS3 where you could create a disk image that has the software each node will run. But GNS3 and Cloonix use full virtualization so use more resources. By canvas, you exactly mean an independent physical server with an interface card even though that interface card will be bound to a single ip?

I am going to look into CORE, and try to do exactly what you suggested. If you are using physical machines then see my other reply about the physical setup. I suggest you read through the GNS3 posts on this blog. No coding is required to use GNS3. Hi Brian, Thanks for the useful post. Hi Farid, Any of the simulators I have written about except for Psimulator2 would probably meet your needs, depending on the details of your requirements. Congratulations for taking the time to create such an amazing content, and to share it with the whole Internet.

Hi Hilton, Thanks for reading my blog. But since lower layers tend to be more reliant on specific hardware, I am not sure I will find any that are based on open-source software. My bad, I missed this for so long time. For education purpose, I am trying to create a framework for this purpose. Hi Parthiban, Thanks for your comment. I need to know which network automation tools you are considering before I can advise you. Some network automation tools like Ansible, or Docker effectively do the same work as the network emulators I reviewed in this blog: they set up hosts and create networks between them in an automated fashion.

I do not know how well this will work. Good luck. Hi Brian please suggest any simulator which can record energy consumption of routers in backbone networks. I could not find energy model for wired networks in ns2. It simulates the energy consumed by virtual data center IT equipment, such as compute servers, network switches, and communication links.

The CORE network emulator is also useful for emulating a wireless mesh network but does not emulate the radio part. Hi Brian!! Hello thanks for informative article could you please help me to get the names of open source multimedia simulators for networking Which can be used to send audio video messages..

Thanks for keeping this blog. It is wonderful to find this much good info and experience in one place. I will, hopefully, be doing some of this in my job in the very near future. The key distinction is the ability to create test-beds for physical hardware and systems under test. How do I find this information out? Think of it this way: if I shoot you with a good emulation of a gun, it will probably — literally — kill you. You can find more cisco network diagram templates and examples in creately diagram community.

There are s of examples and template to be used freely. OPNET is a commercial product. The only open-source emulator that may meet your needs is CORE. But I would very much appreciate your feedback on this matter in case you have other suggestions?

Thanks a lot! I agree that emulating an LTE network is a complex scenario. You would need to find open source implementations of LTE protocols. I am not aware of any. I think NS3 is the most likely to work because you may write your own code to simulate the LTE network. Thanks as I wait in anticipation for your reply. My mail is lpeegroup gmail. I do not think that any of the emulators in this list would emulate a standard large-scale WLAN network succesfully. Using this tool, researchers may emulate a Wi-Fi link between virtual machines.

Some practical examples and supporting information are at the following links: lab , thesis , hostapd , wpa-supplicant , docs-1 , and docs However, you said you are working on a WLAN that will serve a very large school. Then I suspect you would be looking at commercial solutions with high-capacity access points, and WLAN controllers. If you need to emulate this system as part of your planning process, I suggest use the ability to emulate the solution as one of the requirements when you go looking for vendors.

I want to use a network emulator where I can add some new devices from non standard vendors. Then using my application I want to get the configuration or attributes to generate configuration in a file. Can you please suggest me any emulator where we have APIs to communicate or can be used to complete the purpose?

Cloonix supports adding node configuration commands to the project file. Can u tell which simulator is required and how to do integration of that simulator with SUMO. Hi Brian, Thank you for the great post. So, I would like to hear your opinion on the subject below. My group is working on development of smart SDN applications, specifically targeting network health analytics and traffic redistribution. Great website. Thanks for pulling all these in a single location.

Knowing about these other opensource options is great. Like a buffete…. Hello Brian, Thank you for this informative post. My research is on software defined mobile networks, where I propose an architecture of distributed controllers. So, from your experience, what tool can provide me with such feature? Generally, most of the emulators I discuss are best used for Layer 3 and higher. You may want to look at mininet-wifi to see how it emulates the wireless Ethernet link layer….

I am thinking of it to be like a overlay network of internet nodes running new multicast protocol. This means, at the destination, I can incur packet loss, delay, corruption etc. Which simulator is recommended?

If you need to modify the kernel, you will need full virtualization. If you need to perform discrete time simulation, then only NS2 or NS3 may be used. Maybe you could save me a bunch of time and make a recommendation for me. Seeing how well or poorly they perform in a stable and unstable network environment would be valuable too. But, the simplest case is to use GNS3 or Cloonix. These offer full separation between virtual machines. If you need to use a discreet-event simulator like NS-2 or NS-3, then I do not have an opinion because I have not used those tools very much.

NS-3 is the newer version so maybe you should use the tool that is currently supported NS It may not produce perfectly repeatable results but it will allow you to set up test much more quickly. We then tie the two datasets together for reporting. Hi Clinton, Yes, most of the emulators listed on this site could also be used to generate traffic. Hi Guys, Can anyone suggest a simulator for simulating energy networks particularly smart energy networks, I am looking to create a simulation for home networks.

Target is to simulate home IOT nodes Any device with a sensor, whether it is a smart meter or any other home appliance. I researched that NS3 can simulate energy networks but not sure whether it can simulate energy networks or not In my case home network. Which net sim would you recommend to do the same with ip-based networks? Hi Daniel, Cloonix includes a feature called A2B that will allow you to configure link attributes links. I started the simulation and ran iPerf between the two docker containers and it worked perfect.

I remove the links parameters and everything works again… any suggestion? I suspect this is an issue with the way tc works with Docker containers. Can you help me with that please? I need to know which one is easiest on config, run and test.

Thank you my good friend. I assume your software testing must be rigorous and repeatable. NS-3 is complex and I do not have any experience using it. But it is used by academics around the world because it offers repeatable results. NS-3 can also support different link-layer protocols besides just Ethernet. On the other hand, network emulators are easier to use. Most are limited to experimenting with Network-layer and higher layer protocols.

The emulators I review in this blog use Ethernet as the Link-layer protocol. Assuming that we do not use GN3 unless it is absolutely necessary. If you will use traditional virtual machines, use Cloonix. Actually, Cloonix also support containers. If you will use namespaces, the building blocks for containers, then use CORE. Maybe worth updating their website? I see there are more than comments on this post, which is repellent to read, although there are precious information. Maybe you could refactor these into dedicated question pages in a stackoverflow way?

And instead of refreshing this post, maybe you could create a new post one per year? Hi Romain, Thanks for all your suggestions. When choosing which tool to use, use the one that uses technology you are most comfortable using and debugging example: namespaces versus Docker.

Please I am looking forward for your advice. Thank you. You can emulate a normal router in Mininet. Any idea? Please reply if you have any idea. Are any of you familiar with ns-3? I want to simulate a network and compute link delays and some other metrics but I need some assistance in this matter. Hi Nadir, I hope you find the answers you need. NS-3 is more complex than most of the network emulators I have written about in this site. Since the learning curve is long, I have not yet tried NS Hi Brian, I really like and appreciate your discussion forum.

Thank you in advance, Kebebew. Hi Abdul, New York University recently released an open source end-to-end network simulator for 5G mmWave cellular networks based on the NS-3 simulator. See the article on the NYU Wireless web site. Also the project is hosted on GitHub. Thanks Brian for the great exposure. I wonder what programming languages and tools are used to build such simulation software in windows and linux? Thank you for this informative post.

Your website is a great website and once again for putting these together in one location. And in addition,which open source lab. Thanks for your comment. Most people studying for certification exams use GNS3. The GNS3 web site also offers active forums where you can get help. Hello Brian, Thanks for the informative post.

I look forward to using deep reinforcement learning algorithm clipped double deep Q-learning to design a task scheduler for cloud resource allocation. Can you suggest, which one would fit best for my work? Will appreciate if you can evaluate YANS and give me feedback. If you find it useful, feel free to include it in your list. Hi Kenneth, Thanks!

I will check it out in detail probably later in February. I have a current location and I want to practice if it goes down. How can I switch networks for my users. I like the tools they are so far a little lite on features. This sounds like a good plan.

The ns-3 has an emulation mode execution set up where the ns-3 net devices can be connected to LXC via tap-bridge. In my research work, I may need to deploy 1k to 10k Linux containers. Can you help me or show me how the Linux containers can be integrated to the ns-3 simulator?

Hello Brian. So I need a simulator to run my algorithm. Can I use any network simulator to design a distributed OS algo? Hi Brian, great info you got here. I build my own network topology and put the link bandwidth Mbps and when I test the throughput using iperf command between two hosts, I get very small value about kbps.

Why I got this small number? I appreciate your help Regards, Heba. Great article!! Hi Brian, I am trying to find a suitable network simulator for optical networks that can offer QoS for real time multimedia streaming applications. Hi Paul, No, I am not aware of an open-source network emulator or Simulator for optical networks. HI sir , I have to work in Except ns3 , what can we use to simulate? Hi I want to try network programming.

Which one would be the best to use for network programming? Can you provide your opinion on this? HeyBrian Can you Give Me tool That helps manages networks like viewing routers if it has a connection per floor. It can be link or link also because im working for my capstone and thesis. Can you suggest some open source tools to simulate and emulate such behaviors virtually without the use of real physical devices.

This is for testing and development purpose only. Hi Brian Thank you for this nice post. Second, What is the best tool to simulate SDN network to monitor the behavior of network to define the optimal placement of the controller based on dynamic traffic. Hi Nasser, Thanks for your interest. My blog does not cover commercial network emulators so I cannot comment about OpNet. Any network emulator may be used to evaluate performance. Mininet is designed to support SDN network emulation so it is probably your best open-source option.

If you need reproducible results that you might use in a research paper, you must use a simulator like NS I do not know enough about NS-3 to recommend any specific path forward with that tool. I have developed network simulation for ten years by opnet.

I want to build a network attack and defense platform. Can you give me a suggestion? Which tool is better? By the way, are you familiar with emulab and ToMaTo Testbed? At some point in the future, I plan to investigate whether ToMaTo can be installed and used on a single laptop computer.

I understand that emulab is a research platform and is not available to individuals like me. I cannot recommend a specific emulator because I do not know all your requirements. I suggest you consider what type of virtualization best meets your requirements and use that as a basis for choosing the emulator. Hi Brian: First of all thank you for your reply. I want to find a tools for supporting large scale network simulation and support dock use it to Load own applications and distributed support for multiple emulator.

For my final year, I am required to do a Research Development Project which is based on Penetration-Testing for my dissertation. Please check this new simulator. Hi Victor, I looked at the site. Is this an open-source project? I cannot find any information about the license or where to get the source code. Hey How to generate traffic from csv file in mininet. How will I generate the csv file and where will I save it. Maxinet can suported mininet cluter. But I can not Correctly install and running the software.

I hope to get your help. Hi Brian: I know this is a down-in-weeds question but your blog seems to be the de-facto Cloonix support site so I figured I would see if you might be able to help. Unfortunately, the build fails with the following:. This would appear to be a bug in either the latest posted source or the build scripts e.

Any suggestions? Do you know Filius? Hi Jan, Thanks for this information.

See the "Enabling and Disabling Virtual Blades" section. Copies files to the WAE hard drive for use by your virtual blade. You cannot disable a virtual blade on a WAVE device. You cannot configure virtual blades on device groups. The General Settings window appears see Figure Step 4 Check Enable Virtualization to enable virtualization. Step 5 Click Submit. You are prompted to confirm that you want to modify general settings. Doing so will reboot the WAE.

After the reboot, the WAE will have a disk partition and other resources reserved for virtual blade use. Note When you configure a virtual blade on your WAE device, system resources are reserved for the virtual blade. Step 6 Click OK. The WAE restarts. Step 7 Locate the disk or image of the operating system that you want to run on the virtual blade. This section describes how to configure a new virtual blade or edit an existing blade. You can configure resources such as the virtual blade number, description, boot method, disk allocation, and other parameters.

Note that after a virtual blade is initially configured, the only resource parameters that can be changed are memory and the bridged interface. To change these parameters on a virtual blade, stop the virtual blade first, then start the virtual blade after making changes. The Virtual Blade Entries window appears see Figure Any existing virtual blades are displayed in the Virtual Blade Entries list. To get status, see the virtual blade Actions window see Figure Step 4 Click the Edit icon next to the virtual blade that you want to configure, or click the Create button to create a new virtual blade.

The Virtual Blade configuration window appears see Figure Step 5 Configure the virtual blade system parameters as needed to run your operating system and applications:. If you are creating a new virtual blade, type the number of the virtual blade that you want to create in the Blade Number field. The number of virtual blades you can configure depends on which model of WAAS appliance you are using, and the amount of memory installed in that appliance.

Optional In the Description field, type a brief description of the virtual blade. Choose a source for the virtual blade to boot from by using the Boot From list, as follows:. Use this choice after you have installed a guest OS, to boot from the installed guest OS. If you specified cd-rom for the Boot From list, the CD Image setting is required and configures the location of the boot image. The choices for the CD Image are as follows:. If you want to reserve resources for a virtual floppy disk on your virtual blade, enter the pathname of the floppy disk image in the Floppy Image field.

In the Disk Space field, enter the size of the virtual hard disk, in Gigabytes, that you want to allocate for the virtual blade. You can configure up to four virtual hard disks on the virtual blade by specifying four hard disk sizes, separated by spaces, as shown in Figure In the Memory field, allocate the amount of WAE memory, in Megabytes, that you want to make available for the virtual blade.

The amount of memory that can be allocated for a virtual blade depends on the amount of memory in your WAE or WAVE appliance, and on the amount of memory that is assigned to other virtual blades. The minimum amount of memory that you can allocate for a single virtual blade is MB.

In the Disk Emulation list choose the type of disk emulation that the virtual blade uses. Choose IDE or virtio. Virtio specifies a generic disk controller emulator optimized for virtual machines. If you select the virtio emulator, you must have the paravirtualization PV drivers installed on your system.

On the NIC Emulation list, choose the type of network interface card emulation that the virtual blade uses. Choose rtl , E , or virtio. If you choose the virtio emulator, you must have the paravirtualization PV drivers installed on your system. Choose qemu64 for a bit processor emulator or qemu32 for a bit processor emulator.

Step 6 Configure the interface bridge you want to use between the virtual blade and the physical interfaces on your WAE by doing the following:. In the Virtual Interfaces pane, click Add. The Virtual Interface Add pane is displayed see Figure In the Interface Number field Enter the virtual blade interface to be bridged. Valid values are 1 or 2. In the Bridge Interface list, choose the physical WAE interface that the virtual blade interface is bridged to.

Choose either GigabitEthernet or PortChannel. Click Add to List to add the virtual interface to the virtual blade interface list. Note To access the virtual blade console use the IP address of the bridge interface, with the virtual blade number specified as the port number separated by a colon. Step 7 Choose the virtual interface by clicking its radio button on the display.

Step 8 Click Submit. The Virtual Blade Actions window appears see Figure Step 4 In the Virtual Blade list, choose the virtual blade that you want to enable or disable. The status of the virtual blade is displayed in the Status field. The default selection for the Virtual Blade list is All. When All is selected, the Status field displays the current status for all virtual blades. Step 5 Click Start Virtual Blade to enable the selected virtual blade.

The General Settings window appears. Step 4 Check Enable Virtualization to enable virtualization. Step 5 Click Submit. You are prompted to confirm that you want to modify general settings. Doing so will reboot the WAE. After the reboot, the WAE will have a disk partition and other resources reserved for virtual blade use. Note When you configure a virtual blade on your WAE device, system resources are reserved for the virtual blade.

Step 6 Click OK. The WAE restarts. Step 7 Locate the disk or image of the operating system that you want to run on the virtual blade. This section describes how to configure a new virtual blade or edit an existing blade. You can configure resources such as the virtual blade number, description, boot method, disk allocation, CPU list, and other parameters.

Note that after a virtual blade is initially configured, the only resource parameters that can be changed are memory and the bridged interface. To change these parameters on a virtual blade, stop the virtual blade first, then start the virtual blade after making changes. The Virtual Blade Entries window appears see Figure Any existing virtual blades are displayed in the Virtual Blade Entries list. To get status, see the virtual blade Actions window see Figure Step 4 Click the Edit icon next to the virtual blade that you want to configure, or click the Create button to create a new virtual blade.

The Virtual Blade configuration window appears see Figure Step 5 Configure the virtual blade system parameters as needed to run your operating system and applications:. If you are creating a new virtual blade, type the number of the virtual blade that you want to create in the Blade Number field.

The number of virtual blades you can configure depends on which model of WAAS appliance you are using, and the amount of memory installed in that appliance. Optional In the Description field, type a brief description of the virtual blade.

Choose a source for the virtual blade to boot from by using the Boot From list, as follows:. Use this choice after you have installed a guest OS, to boot from the installed guest OS. If you specified cd-rom for the Boot From list, the CD Image setting is required and configures the location of the boot image. The choices for the CD Image are as follows:. If you want to reserve resources for a virtual floppy disk on your virtual blade, enter the pathname of the floppy disk image in the Floppy Image field.

In the Disk Space field, enter the size of the virtual hard disk, in Gigabytes, that you want to allocate for the virtual blade. You can configure up to four virtual hard disks on the virtual blade by specifying four hard disk sizes, separated by spaces, as shown in Figure In the Memory field, allocate the amount of WAE memory, in Megabytes, that you want to make available for the virtual blade. The amount of memory that can be allocated for a virtual blade depends on the amount of memory in your WAE or WAVE appliance, and on the amount of memory that is assigned to other virtual blades.

The minimum amount of memory that you can allocate for a single virtual blade is MB. In the Disk Emulation list choose the type of disk emulation that the virtual blade uses. Choose IDE. Virtio specifies a generic disk controller emulator optimized for virtual machines.

Note If you select the virtio emulator, you must have the paravirtualization PV drivers installed on your system and you must validate this configuration. Virtio for disk emulation is provided on an experimental basis only and is not a supported feature. On the NIC Emulation list, choose the type of network interface card emulation that the virtual blade uses. Choose rtl , E , or virtio.

If you choose the virtio emulator, you must have the paravirtualization PV drivers installed on your system. Virtio for NIC emulation is provided on an experimental basis only and is not a supported feature. Choose qemu64 for a bit processor emulator or qemu32 for a bit processor emulator. Step 6 Configure the interface bridge you want to use between the virtual blade and the physical interfaces on your WAE by doing the following:.

In the Virtual Interfaces pane, click Add. The Virtual Interface Add pane is displayed see Figure In the Interface Number field Enter the virtual blade interface to be bridged. Valid values are 1 or 2. In the Bridge Interface list, choose the physical WAE interface that the virtual blade interface is bridged to.

Choose either GigabitEthernet or PortChannel. Click Add to List to add the virtual interface to the virtual blade interface list. Note To access the virtual blade console use the IP address of the bridge interface, with the virtual blade number specified as the port number separated by a colon.

Step 7 Choose the virtual interface by clicking its radio button on the display. Step 8 Click Submit. The Virtual Blade Actions window appears see Figure Step 4 In the Virtual Blade list, choose the virtual blade that you want to enable or disable. The status of the virtual blade is displayed in the Status field. The default selection for the Virtual Blade list is All. When All is selected, the Status field displays the current status for all virtual blades.

Step 5 Click Start Virtual Blade to enable the selected virtual blade. The startup delay can be used to give you time to connect a VNC session to the console before the virtual blade boots, so you can observe the initial startup. Step 6 Click Stop Virtual Blade to disable the selected virtual blade. The shutdown timeout provides a delay period during which the operating system can shutdown gracefully.

If the operating system has not shut down the virtual blade by the end of this period, WAAS forces the shutdown. A forced shutdown is comparable to pulling the power cord on a real computer. To avoid losing data in open programs running on the virtual blade, it is safer to have the operating system perform the shutdown. Step 7 Click Refresh Status to refresh the status of the virtual blade after you make a change.

Note The operating system on your virtual blade does not shut down and restart when you reboot a WAAS device.
