Public bug reported:
Hi,
I am using Xeon 6430 (SapphireRapids) cpu in my server. I am using is
node as a compute node. I am using ubuntu jammy and libvirt
8.0.0-1ubuntu7.10.
The output of "virsh capablities" show "SapphireRapids-noTSX" as cpu.
While "virsh domcapabilities" shows "Icelake-Server" as host-model.
The VMs spawn on this host shows Icelake-Server cpu.
When I use custom cpu mode in nova.conf as sapphire rapids, nova-compute
fails to start.
