Replying to my own post here, I've verified that it's
currently not
possible to do a greenfield deploy of oVirt 4.4.0 w/ hosted engine on EPYC
CPUs due to the system setting a requirement of 'virt-ssbd' for the final
HE definition after the move to shared storage. The local HE runs perfectly
through the setup process because it correctly uses 'amd-ssbd' but
unfortunately that doesn't stick after the disks are moved.
You can work around it via 'virsh -r dumpxml HostedEngine > /tmp/he.xml',
then editing that file to simply change 'virt-ssbd' to 'amd-ssbd'. Start
it
via 'virsh create /tmp/he.xml' and now it runs fine. You can get into the
admin interface and if you want to run something hacky could at this point
change the cluster CPU type from 'Secure AMD EPYC' to just 'AMD EPYC',
take
everything down and bring it back up cleanly... hosted engine will now work
because the requirement for virt-ssbd (not available on EPYC when using
CentOS 8.1 or presumably RHEL 8, amd-ssbd is needed) is gone.
I would like to test it during final stage of deployment, but the "virsh
create" command requires a password.
[root@novirt2 log]# virsh create /tmp/he.xml
Please enter your authentication name:
I don't remember how to setup a user so that I can run it on oVirt host..
any input?
Just for my testing lab in 4.4. obviously...
