I'm writing this comment from a Windows 10 VM within CML! I played around with this tonight. It looks like the poor performance on startup is due to massive CPU usage. I spun up 8x Win 10 nodes (running 16 vCPUs on a 14c/28t chip) just to test, with the only difference being I gave them all 4GB instead of 2GB. The CML Lab Manager and Windows Task Manager both showed that they all stayed spiked at 100% CPU load for a number of minutes (even after the system was up and running) before they settled down. The best I could tell, it was more than one program, but Microsoft Defender was one of the biggest culprits that I saw. I also noticed that if you only give them 1 CPU core each, they will BSOD on startup. So, each Windows 10 VM you spin up is going to eat two full cores for a while. Fortunately, it eventually settles down. Thanks for the great video David! I never got Windows to work on 1.x. I'm so happy that I'll have a working Windows VM in order to easily test things. It's also the first time I got the external connection working right. You even got a shout-out from Keith Barker tonight for your great CML videos.

Thank you so much. I was able to pull enough out of your VERY detailed session, that I was able to import Palo Alto Networks firewalls and integrate them into my CML lab for design testing.
Hey, this is an old comment but I too imported and am trying to run PA. I am importing WIndows right now to fix a problem I have... PA boots, and then you have to connect to the 'mgmt' port to configure it's IP interfaces, otherwise no interfaces appear in the CLI. How did you accomplish the initial configuration of your PA firewall? I can give it an IP, but even over an external connector (one where I can connect to other systems in CML just fine) I cannot connect to the PA FW, because none of it's interfaces are this 'mgmt' port.
I tried this again, and I while I love having Windows as a host, I am not really happy with the high CPU usage of the Windows VM. It's staying spiked at 100% for a LONG time. So, while I was researching, I found that EVE-NG has a qcow2 image of Ubuntu Mate 20.04 for download (2GB). I installed this the same way (using your video as a guide), and I was able to get Ubuntu Mate up and running. This booted up much faster, and it consumed far less resources. RAM usage was only ~675MB (compared to about 2GB on Windows). CPUs were idle pretty much immediately (and I mean 0-1%, unlike the 20-30% on the Windows VM after about 15 minutes of 100%). And unlike the built-in Alpine Desktop image, you can actually see the network card settings within the VM. I'm going to keep both images, as I like having options. However, I'm thinking I'm going to like Ubuntu Mate when running the labs. I still can't thank you enough for this video. I'd never know how to add either image without your help.
Excellent videos David. I was looking to run Cisco SDWAN (Viptela) on Virl 2 and I can't find much documentation or videos about this topic. It will be great if you can record a from steps by steps or "A to C" in how to do so. I have a lot of engineers friends interested on this topic. Hopefully this message gets to you. Thanks again for this great channel!
Amazing content here David, Can't wait to give it a try! Quick question if that's ok? Do you need two physical machines for this lab, or can this lab be all done from one laptop?
No - just run everything on one computer. I am only using two computers as I use a Mac as my main computer, but most people use Windows. I therefor carry around the extra Windows laptop so I can demonstrate stuff for Windows' users :)
This is another complicated thing David makes easy.... Works as a diamond with version 2.6, thank you... I will try to do similar thing with win server and ise
Thank you for making this! I was trying to do something silly and create a bunch of flat networks in the UWM to connect Microsoft VMs. Definitely not scalable.
HI David, first of all, love your videos! Second, I've been trying to perform these steps so I can have a windows image on CML. But I'm having trouble with copying the qcow2 file to the CML server. The windows machine from which I'm trying to upload it doesn't recognizes the scp command. Any idea's or thoughts to fix this? Edit: Figured out it was just a matter of installing Putty and using the command pscp -scp instead of just scp. Thanks anyways! :D
great video, I think I can use this as a template to upload other devices such as juniper or Arista. Question, do the .virl files from the 1.6.65 version work with the CML 2?
SSH credentials. Hi, first of all great content! I'm trying to SCP an image to the CML server but my credentials fail. I've tried SSH'ing in too-same result. The same credential give me privilege access to the Cockpit so I'm not sure what has happened. Any idea if there has been a change on the upgrade to CML2.1.2? Thanks
Hello Mr David and thank you for your great videos. I want to make a question could I run Docker containers on Cisco CML ; Thank you again and keep up the awesome work you are doing .
I am trying the method for FMC and FTD. Any tips on the Node Definition creation? Might be worth doing a video just on Node definition creation. Not sure how to decide what the VM needs. Trial and error?
Good day David Thanks for all your amazing videos. You have really been helpful in my career. I had a question about CML. I currently had a virtual iso of windows 10 installed on my server. I can't seem to get the cisco anyconnect client to work. I keep getting the same error anyconnect was not able to establish a connection to the specified secure gateway. I turn off my firewalls and anti versus on my windows iso. Can you help me with this issue, please?
Excellent as always thanks david. Roll on Tuesday 12th will be ordering CML and using your vids for setup so thank you. Do you no release time? And if it be on same site that current virl is on?
Hi David, Thanks for this great video I tried to make it work, but like many users i see on different posts when i boot up the VM it tells me "no bootable device" I tried many different configurations (Image definitions in IDE/SATA/VirtualIO), nothing changes I read somewhere that the Cisco CML VM itself had to start in BIOS mode instead or EFI and that it would correct it but when doing so its the Cisco CML VM that tells me that there is no bootable device (here also i played with many settings in VMWare ESXi v8 (ide configuration of the hard drive of the CML VM)) but here too nothing changes) Any clue on how to get it work ? I think many users are facing the same issue Thanks !
Just figured it out Guys : * The thing you need to do is the following : download an iso image of windows from microsoft's site (not an ova) * Pop a windows VM with the iso image mounted in your virtualization environnement and specifiy "BIOS" in the VM Options > Boot Options > Firmware Type * Once intalled, convert the vmdk file created in qcow2 (you have to download it from your virtual environnement and apply David's video command to launch the conversion) * once converted, the rest is like David's video Works for me.
Hi David, is the 20 node restriction related to Cisco images only? i.e. i could potentially have 10 non Cisco devices running and 20 Cisco devices running and still fall inside the max node restriction? Thanks in advance.
It is Cisco nodes and other bespoke devices that you add if I understand the developers correctly. So, you could have 20 Cisco devices and 10 of the inbuilt Ubuntu servers, but you cannot have 20 Cisco and 10 Juniper devices for example.
Does every instance of a Windows host in your CML lab take up 20GB? If it did, then a large network full of Windows hosts could not run on a normal home PC even if it had 64 or 128GB of RAM.
@David Bombal Is this supported for Fortigate VM? There doesn't seem to be an applicable simulation driver in the list under Node definition. Also, I didn't use the SCP option, under manage upload images there's an upload button which browses your local machine for .qcow/qcow2 files.
All versions of IOS are included with CMA,2, or is it just all versions supported? What is the minimal version of Fusion to safely run Virl2 or GNS3, etc?
Hey David, I'm trying ur method now but I cannot boot the VM. It shows SeaBios no boot device found. Do you know of any fixes I can try? I did two variants, one with Microsoft's own Eval machine and my own VM which I exported and converted the VMDK to qcow2. The one I created is the one that could not boot up
Hi david, same approach is works on Gns3 but windows 10 works so slow on gns3. I use it so I can have the Gui of multiple appliance easily. Any sugesstion plz?
It will be the same issue on all of them GNS3/EVE-NG/CML when you run the Windows VM on their VM. This is because they are nesting Windows within another VM (GNS3 VM / CML VM / EVE-NG VM). I typically use GNS3 locally on my laptop and then use an external VM in VMware (not running within the GNS3 VM) to add to my topologies. That way the VMs run quicker. So, the Windows VM is running locally alongside the GNS3 VM, not added within the GNS3 VM. That is quicker.
You can SSH and VNC directly to devices and open multiple sessions. See this video where I demonstrate the breakout tool. I am using Putty, but you could do the same with VNC: th-cam.com/video/uE7-FgLxlyk/w-d-xo.html
When I am at the step shown at minute 23:06 in the video and it asks for a password; what password is that? It is the Windows Command Prompt. Why would it be asking for a password? The password for logging into Windows? The password for logging into CML? The password for logging into the Centos Linux page? None of those passwords work for me. But the last time anyone replied to this video was a year ago. I hope someone checks and replies to my question or else I just wasted tons of time on this for nothing.
@@davidbombal Was that because of the low amount of RAM you gave it, or was it whole nested VM thing? I just built a Core i9-10940x (14 core) with 64GB of RAM. Testing my overclocks now. Waiting for the new release of VIRL (errr, CML-P). I'm hoping my hardware can muscle through any speed issues.

Is it possible to use other appliances too, in eve-ng we also have to convert the files to qcow.
For example checkpoint firewall ?
The developers have told me you can, but I haven’t tested myself. But you should be fine
for some reason, my vmdk file isn't compacting much. i even tried using "sdelete -z c:". no idea what might be happening.
All versions of IOS are included with CMA,2, or is it just all versions supported?
What is the minimal version of Fusion to safely run Virl2 or GNS3, etc?
Just specific supported images. Fusion 10 or later is required for CML
