Hello all,

It looks like upstream still will not take this change, so I am working on a fix for it in Ubuntu specifically. In the meantime, I've created a PPA (https://launchpad.net/~lvoytek/+archive/ubuntu/libvirt-add-icelake-10nm-to-cpu-map) that adds two new CPU models for 10nm Icelake:

Icelake-Server-noMPX
Icelake-Server-noTSX-noMPX

These can replace the use of Icelake-Server and Icelake-Server-noTSX respectively. If you would like to test the change in 20.04, 22.04, or 22.10, then you can add the PPA to your system with the following commands:

sudo add-apt-repository ppa:lvoytek/libvirt-add-icelake-10nm-to-cpu-map
sudo apt update

Thanks for your patience
