Creating A Custom Image in Cisco Modeling Labs
มุมมอง 4.1K2 ปีที่แล้ว
This video shows how you can create a customized image using a existing base image, and then save those customizations with the "qemu-img commit" command. We look at the base Ubuntu 20.04 image, add some packages to it, and then save the result so we can spin up multiple images without needing to wait for those same customizations to be applied.

how do you get access to System Administration Cockpit ? I try to. use mi. local cml password but I don't have any access
The username is sysadmin and the password is what you set during install time.
Thanks for the video!
This channel is super underrated! 😎
Thanks!
Awesome work! Thanks a lot! I am running CML in a Bare Metal UCS Blade. And CML was going down after it trunking an external connector, I just had to wait to normalize...
I got totally lost on this. I'm running CML for the first time and I went with the default of everything. Now you said that VMs can't be run on the controller but my cml-controller says it has a total of 4 of 6 VMs running. All I'm trying to do is get this Cisco lab up and running but I am having this issue with "Failed to choose a suitable compute node (insufficient HW resources)" issue.
using CML as a test environment and have some outside non-cisco VM's functioning as routers that couldn't be replicated in CML. I know this video is 3 years old but this just saved me alot of time and allowed me to successfully trunk replica's of them into the test environment lab. Thank you.
Thanks for sharing xorrkaz. The video came in time for me.
I've been trying to figure that out and was not able to find an answer until today. Thank you!
How we upgrade cml fro ver 2.5.3 to 2.6
You can do an in-place upgrade using the .pkg file starting at Tools > System Upgrade
@xorrkaz Dude, you don't know what you just did for me!! I've been wiping my manually configured nodes (Win10, win server, and Palo Alto) probably like 5-6 times so far because I thought Cisco engineers weren't smart enough to allow for vCPU and RAM increases without nuking the whole MFing node. THANK YOU from the bottom of my heart! You are a savior
I noticed you had 80 nodes. Which version of CML are you using? If I start with the smallest 20-node version, may I upgrade to 50, 60, or even 80 nodes as time progresses? Thank you for your wonderful videos!
I am using a CML Enterprise license. CML Personal only comes in 20 and 40 node versions (Personal and Personal Plus). Enterprise is scalable up to 320 nodes.
You rock, after watching your video I was able to get it working in less than 2mins. Very unfortunately I wasted 5 days trying to get this working on my pfsense - VMware - CML.
HI Joe how would you go about connecting your ubuntu node to the internet using external connector
Same as with the standard Ubuntu node. Just connect it to the external connector and configure the interface based on the ext-conn type.
I trying to connect the Ubuntu server to the external connector in bridge mode for a project but keep getting host unreachable
@@mohamedahmeddahir9463 If deployed on ESXi, you need to enable promiscuous mode and forged transmits for the port-group.
Does this apply to CML running of VMware workstation pro ?
@@mohamedahmeddahir9463I don't think it applies to Workstation. I know Fusion doesn't have such an option. Though you'll want to make sure you're bridging within VMware and not sharing your host's connection since that would require additional NAT.
Love the video Joe! I'm looking forward to making my own custom desktop images. One question... How would one go about exporting an updated qcow2 file to keep outside of CML? I'm thinking if I ever had to blow away my CML VM, I want a copy of my new image that can be re-imported.
You can grab the images from that /var/lib/libvirt/images/virl-base-images sub-directories. You can use SFTP to pull them off the system.
@@xorrkaz So, it looks like those are .img files. I'd just need to convert them back to .qcow2 and I'm good?
@@playloud90278 Those .img files are still qcow2 just with a different extension. You can just rename them if you like.
@@xorrkaz Even better! I'll give that a whirl this weekend. Thanks!
Thanks Joe, nice overview.
Is there a way to add notes like text boxes?
This is coming in the 2.5 release due out early next year.

Any idea how I can resolve inserthostname_here> while accessing iosvls (switch)?
I have Problem with configuration, some devices doesn‘t work. The setup ist complete and the lab is ready for use .so what is the rong Thanks
Thanks xorrkaz, are there any gotchas that I should pay attention to ?
Nothing relevant to SD-WAN.
I can see your SD-WAN node definitions in your list, did you create these as custom definitions?
You can find these node definitions at github.com/ciscodevnet/cml-community.
I am new to this setup, can you recommend a pc that can handle setting up CML. Currently having issues finding a processor to turn on Vt-x
hi thank you very good video
Can i use this as a Packet Tracer?
This is not like Packet Tracer. CML orchestrates full instances of the core network operating systems as virtual machines, whereas Packet Tracer pretends to be network devices by emulating CLI commands and some underlying functionality. As a general rule, you can take advantage of more network features using CML than you can with Packet Tracer.
@@xorrkaz is CML in is on subscription basis.
@@innocentdoodles1938 Yes. CML is licensed annually.
@@xorrkaz will I get nodes like asa firewall, wireless access points, Nexus switches.
@@innocentdoodles1938 You will get ASAs and Nexus switches. There are no virtual APs.
Looks good. I got an older version back in 2020. never got a chance to use it much but this newer version looks good. laptop is i7 and 16 gigs of ram. hoping its enough. may use for CCNP encor.
This is great and thank you. It didn't work for me though I got this warning: "Migration between version is not supported. Source server version: 2.1.1-b19, Dest server version: 2.3.0+build22." Do you know of any work around's?
You need to upgrade to 2.2 first. Migration is only supported from 2.2 on.
@@xorrkaz that’ll do it, thanks
would you able create SD WAN using CML
Viptela nodes and images do work within CML. The images are not included by default, but if you have access to download them from Cisco.com, then you can add them to CML. Node definitions for those images can be found at github.com/CiscoDevNet/cml-community/tree/master/node-definitions/cisco/sd-wan.
@@xorrkaz i already imported them to cml but seems they stuck after a while, please let me know if works for you
@@newvision1571 I do have it working in CML. But note: vManage takes a large mount of resources (8 vCPUs and 32 GB of RAM). So you need a very powerful server to run a full SD-WAN topology.
@@xorrkaz thanks so much for your feedback, and what about SD WAN interconnection, how connect vEdges through vManage? do you think its applicable to run full SD WAN topology using CML
Hello thanks for your videos on CML i love them, would you support me on how practicing SD-WAN on CML considering sd wan nodes already imported to CML and working fine. waiting your kind reply
Hello, I have an issue related to Trex in cml. When I try to connect from the Trex GUI it gives me the following error: Error while verifying the Async request: no response from server. Any suggestions to solve the problem, ? I am using windows 10 OS, cml 2.2.3, and the Trex is 2.88. If you give your email, I'll send you a screenshot of the issue. Thanks
TRex 2.88 is not compatible with the currently release UI. You either need to continue to use the previous version of TRex or compile the latest UI Java code.
@@xorrkaz thank you very much for the reply. Do you know how can I get the previous Trex because I'm running Cml 2.2.3 and Trex 2.88 comes with the latest iso file by default?
@@karrar3156 The CML download site has previous versions of the refplat ISO you can use.

It sounds like the CML controller service is crashing. Go to learningnetwork.cisco.com/s/topic/0TO3i00000094ZoGAI/cml-personal-2x and post your error along with the version of CML you're running. You should also post the log bundle you download from the CML tab in Cockpit.
is it good than eve or unl????
Great content
Ralph is a fucking hero! Such a legend!!
Shoot, Was hoping this could get around that limitation. I love CML because of ease of use but will probably have to migrate to EVE-NT so that I can deploy larger topologies.
The only way to increase the Personal license limit is to upgrade to Personal Plus, which gives you a 40 node limit.
Does connecting multiple labs together overcome the 20 device limit in CML ?
No. You're still limited to whatever your license allows.
thank you for the video
This process works for 2.2.1 version also, Thank you
How you downloaded the RPM file. I purchased 2.1 in January. But when I tried to download RPM file to upgrade to 2.2 , it is asking for a service contract. I only have the order number which I purchased 2.1. Can you kindly tell me the way to download the rpm file.

Thanks for the video!
Thank you, this helped me immensely! It is really difficult to find "how to" videos and documentation for CML administration and this video is great. Can you point me to any resources you use to learn about CML administration?
The admin guide is the currently the best resources: developer.cisco.com/docs/modeling-labs/#!cml-administrators-guide
Hi. It's a very useful video for cml users. Could you guide me to input sdwan (vbond, vmanager, vsmart and vedge) to cml?
While you need to have download access to the SD-WAN QCOW2 files from Cisco.com, you can find node and image definition files to use within CML at github.com/CiscoDevNet/cml-community. There are READMEs there, too, that provide more information.
Is it supported KVM hypervisor now ? Thank you in advance.
If you use the bare metal installer, you could put it inside a KVM VM. However, that is not an officially supported deployment model (i.e., not formally tested).
Hello! I was watching this video and had a question. I am trying to run CML on a vswitch that does not have a physical interface mapped, and following the same concepts in this tutorial are not working (no ping.) Any reason why it has to be there? What else might I want to look at?
Not sure I fully understand. If you're saying you have a vSwitch in ESXi with not physical NIC mapped, what are you expecting to ping? While you could use such a thing to have multiple labs interconnected on the ESXi backplane, you would have to provide either an in-CML DHCP server or assign addresses statically. However, in those cases, you should be able to ping between lab nodes connected to the bridge-based external-connectivity nodes.
@@xorrkaz I am hoping to ping everything else on that vswitch. Forgive me, I didn't provide enough info. I am using this to (try to) connect a CML lab to multiple outside assets. I have VMs all on the same subnet and on the same vSwitch. They are able to ping each other, and able to ping the CML IP I gave to the VLAN adapter, but cannot ping the router on the inside of CML and that router cannot ping out (or, ping the CML IP I gave to the VLAN adapter.) No DHCP on this network, it's all statically assigned. I was wondering if my lack of a physical adapter would cause it, but as I see it this should be just like connecting a bunch of devices up to a simple switch, which as long as they all have an IP on the same subnet / mask should be able to reach each other. I have a topology diagram if you were interested, but can't share via TH-cam comments.
@@Dartagn This is fine. Make sure your vSwitch allows promiscuous mode and forged transmits, and you should be set.
@@xorrkaz I have those set, but still with no connectivity. That's why I had to create the additional vSwitch, because I didn't want to enable those settings on vSwitches with other purposes and VMs on them.
So far so good and thank you for the excellent guide.
Sir great video. I use CML and GNS3 daily. Just recently attempted this upgrade myself and broke CML. Thankfully they recently made it easier to unregister your instances, possible due to the complex steps of this update. Perfect explanation of how to perform this. Keep up the good work. I have a question how would I successful increase the storage capacity of CML through the admin web interface? Currently I am running CML off ESXi right now. Thank you sir, have a great day.
You can do this through Cockpit > Storage after you add a new virtual disk to the VM in ESXi. In Cockpit, Select the mount point "/" and add the new physical volume to the list of physical volumes. Then select the "/dev/cl/root" volume and click the Grow button to have it expand to include the new disk.
@@xorrkaz thank you very much sir. Keep up the great work.
Where can the CML 2.1 Controller RPM file be downloaded from?
CML 2.1 should be downloadable Wednesday October 28.
I love it! These are bigger improvements than we have ever seen from the entire VIRL 1.x history (that I can recall), and in only ~6 months. I'm very happy to see where CML-P 2.x is going. I'm really hoping v2.2 UI will have labels for interfaces, area maps, etc. With the effort that the team now seems to be putting in, I'm excited to see how they implement it.
I hope they add port labels also.
Solid Video!
Just to clarify, you are setting up the Vlan sub interfaces so that the received packets (which are tagged by the physical switch) are processed. Does it untag the packet once it arrives into the topology?
The frames are untagged when they arrive at the CML nodes. The CML VM (Linux) handles the tagging and untagging.
