Hi,
I am using the Proxmox Enterprise repos:
On a new cluster build (7 systems with Intel(R) Xeon(R) Gold 6442Y (2 Sockets))
If I select the SapphireRapids option as the CPU type I get:
kvm: warning: host doesn't support requested feature: CPUID.07H:EBX.hle [bit 4]
kvm: warning: host doesn't support requested feature: CPUID.07H:EBX.rtm [bit 11]
kvm: warning: host doesn't support requested feature: MSR(10AH).taa-no [bit 8]
kvm: Host doesn't support requested features
We usually set the host type so we can migrate from cluster node to cluster node even if future CPU's are newer (when you set it to host and the CPU type 'downgrades' after a live migration you get crashes).
I am not sure if this is a bug or something I'm doing wrong, since the above CPUID bits I can only find related to posts around Haswell.
Per /proc/cpuinfo
Per QEMU
