+++ This bug is a downstream clone. The original bug is: +++ +++ bug 1600573 +++ ====================================================================== similar to earlier Intel CPU update this one is for AMD EPYC family. Microcode update not required +++ This bug was initially created as a clone of Bug #1581144 +++ add SSBD CPUs to the supported list. Requires host support and microcode updates to be effective (Originally by michal.skrivanek)
new type + a fix similar to https://gerrit.ovirt.org/#/c/91615 (Originally by michal.skrivanek)
(In reply to Michal Skrivanek from comment #1) > 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 (Originally by michal.skrivanek)
+ requiring the right rhvm-setup-plugins
testing jira sync, please ignore.
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
