add SSBD CPUs to the supported list. Requires host support and microcode updates to be effective
Comment 1 Michal Skrivanek 2018-07-12 14:14:56 UTC 
new type + a fix similar to https://gerrit.ovirt.org/#/c/91615

> new type + a fix similar to https://gerrit.ovirt.org/#/c/91615

actually, AMD EPYC was new in 4.2 GA and changed there already to use +ibpb instead of -IBPB so just a new type is enough
Comment 3 Israel Pinto 2018-07-16 10:58:08 UTC 
Verify with: 4.2.5.1-0.1.el7ev
Build: rhv-release-4.2.5-3-001.noarch

Steps: 
1. Add host with capabilities:
# virsh -r domcapabilities | grep EPYC
      <model fallback='forbid'>EPYC-IBPB</model>
      <model usable='yes'>EPYC</model>
      <model usable='yes'>EPYC-IBPB</model>
  To cluster AMD EPYC IBPB
2. Start VM on host
VM started and host added 

PASS
Comment 4 Israel Pinto 2018-07-16 11:43:57 UTC 
Moving back to modify verify it on 4.2.5
Comment 5 meital avital 2018-12-10 08:26:14 UTC 
Verified on:
ovirt-engine-4.3.0-0.4.master.20181207184726.git7928cae.el7.noarch

Verification steps:
1) Add host with capabilities:
# virsh -r domcapabilities | grep EPYC
      <model fallback='forbid'>EPYC-IBPB</model>
      <model usable='yes'>EPYC</model>
      <model usable='yes'>EPYC-IBPB</model>

2)Run Vm on the host 

-> Host added and VM started
