<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">hi,
<div>my setup has two computes nodes, every node has a dual AMD EPYC 7601 CPU config. how can i bring all the CPU features (AES, SSSE3, ...) to the guest VMs. i have tryed with some flavor-metadata but nothing realy helps, the VMs getting just a little subset
of cpu-features.</div>
<div>some investigations to the kvm-settings hit me to the facts that my nova config has "cpu_model=none" !? how can i fix that and bring my AMD EPIC CPU to my nova-config?!</div>
