Hello all, Over the past few months there have been a few more reports of users unable to use Openstack Nova on their Icelake CPU. Updating virsh capabilities to properly display that mpx is unavailable fixes it. Is there an ideal way to update this change such that it gets accepted into libvirt?

With the current setup, a 10nm Icelake CPU, such as the Intel Xeon Gold 6338, will be incorrectly recognized by libvirt as a 14nm broadwell CPU due to the mpx label. See https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1978064. When adding the removed tag to mpx in the Icelake xml definition,

[PATCH] cpu_map: Add -noMPX models for x86 Icelake Server

2022-08-15 Thread Lena Voytek
Intel has removed MPX capabilities from 10nm Icelake CPUs[1], which is reflected by the new models through the line marking mpx as removed. The original Icelake Server models have been left alone to avoid regressions. This adds: -Icelake-Server-noMPX -Icelake-Server-noTSX-noMPX References:
