Subject: [Starlingx-discuss] Support IBRS cpu model.
if install StarlingX in compute-node with cpu type 'Skylake-Server-IBRS' , it cannot use 'passthrough' type with keyword hw:cpu_model in favor to create instance
It will prompt "No valid host was found. There are not enough hosts available. computer-0: (VCpuModelFilter) Host VCPU model Skylake-Server-IBRS required Passthrough Code 501"
After investigation , Libvirt 4.7.0 supports *IBRS (for example IvyBridge-IBRS, Skylake-Server-IBRS) CPU model , but nova and meta favor does not support *IBRS CPU model yet.
I have made patch for nova and glance.
Nova will support *-IBRS type vcpu when select passthrough
Glance will add metadata to support *-IBRS in hw:cpu_model
Please review these PRs.
