Hello,

This week I tried to deploy Hosted Engine on Ovirt-Node-NG 4.3.7 based Host.

At the time the locally deployed Engine ist copied to hosted-storage (in my case NFS) and deployment tries to start the Engine (via ovirt-ha-agent) this fails.

QUEMU Log (/var/log/libvirt/qemu/HostedEngine.log) only shows "2019-11-27 16:17:16.833+0000: shutting down, reason=failed".

Researching the cause is: The built Libvirt VM XML includes the feature "virt-ssbd" as requirement, which is simly not there.

From VM XML:

  <cpu mode='custom' match='exact' check='partial'>
    <model fallback='allow'>EPYC</model>
    <topology sockets='16' cores='4' threads='1'/>
    <feature policy='require' name='ibpb'/>
    <feature policy='require' name='virt-ssbd'/>

from cat /proc/cpuinfo:
