Hello, hosted engine deployment simply fails on EPYC with 4.3.7.
See my earlier posts "HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7". I was able to get this up and running by modifying HostedEngine VM XML while Installation tries to start the engine. Great fun ! virsh -r dumpxml HostedEngine shows: <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'/> which is not working. I removed the line with virt-ssbd via virsh edit and then it was able to start Engine. To modify the defined HostedEngine you need to create an account for libvirt via saslpasswd2 to be able to "virsh edit HostedEngine" saslpasswd2 -c -f /etc/libvirt/passwd.db admin@ovirt so your Passdb shows: sasldblistusers2 /etc/libvirt/passwd.db vdsm@ovirt: userPassword admin@ovirt: userPassword If the HostedEngine runs afterwards let it run so it updates the persitent configuration in hosted-storage. I also modified these by untarring and maniplulating the correspondent XML-Strings !. Really ugly and disfunctional.
