Creating A Custom Image in Cisco Modeling Labs

[@playloud90278]

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?

[@xorrkaz]

@@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!

I can see your SD-WAN node definitions in your list, did you create these as custom definitions?

[@xorrkaz]

You can find these node definitions at github.com/ciscodevnet/cml-community.

[@kevinsherwood492]

Thanks xorrkaz, are there any gotchas that I should pay attention to ?

[@xorrkaz]

Nothing relevant to SD-WAN.

HI Joe how would you go about connecting your ubuntu node to the internet using external connector

[@xorrkaz]

Same as with the standard Ubuntu node. Just connect it to the external connector and configure the interface based on the ext-conn type.

[@mohamedahmeddahir9463]

I trying to connect the Ubuntu server to the external connector in bridge mode for a project but keep getting host unreachable

Does this apply to CML running of VMware workstation pro ?

[@xorrkaz]

@@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.

[@newvision1571]

would you able create SD WAN using CML

[@xorrkaz]

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

[@xorrkaz]

@@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.

[@newvision1571]

@@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
