Cisco CML on Proxmox ver 7.x

proxmox Dec 6, 2022

I've spent way to many hours trying to get Cisco Modelling Labs working on Proxmox.

After getting around nested virtualisation I was able to successfully install and boot Cisco Modelling Labs. I could create labs however when trying to console onto a device I would get a blank box, no connection.

I stumbled upon a post - https://pwd.re/posts/cisco-cml-on-proxmox/

It refers to Proxmox ver 7 which uses a Linux kernal 5.22 or newer. After installing 5.11 Cisco CML works flawlessly.

I had to install a new repo onto proxmox

nano /etc/apt/sources.list

deb http://ftp.uk.debian.org/debian bullseye main contrib
deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription
deb http://ftp.uk.debian.org/debian bullseye-updates main contrib
deb http://deb.debian.org/debian bullseye main

Run 'apt update'

Then run 'apt install pve-kernel-5.11.22-7-pve'

When booting proxmox, you hit enter select advanced boot options and select kernal 5.11 (5.22 is selected as default)
