@shubhaOracle @saksham-oracle:
Could you guys check this patch?

I've seen you included a add-sapphire-rapids-server-family.patch in latest Oracle ovirt-engine builds.
But I think that patch is invalid.

+        || '22:Secure Intel Sapphire Rapids Server Family:vmx,arch-capabilities,rdctl-no,ibrs-all,skip-l1dfl-vmentry,mds-no,pschange-mc-no,model_SapphireRapids-Server-noTSX:SapphireRapids-Server-noTSX,+arch-capabilities,+rdctl-no,+ibrs-all,+skip-l1dfl-vmentry,+mds-no,+pschange-mc-no:x86_64; '

You change the flags of Secure Intel Icelake Server Family, and apply the same flags to Secure Intel Sapphire Rapids Server Family.
For Sapphire Rapids you use model_SapphireRapids-Server-noTSX as a base, but that model does not exist in libvirt?! :)

Has this been tested? :)

Also I think it might be better to have a consensus here, cause if flags start to differ between OLVM and oVirt upstream, you might end up with annoying things in the future.

Is there a chance to get this merged/released soon? We're very much looking forward to this change. Thanks!

Also included in the latest ovirt-engine release of OLVM. Except the POWER10 CPU.
