[ovirt-users] Re: HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7

Hi Ralf, When the deployment fail - you can dump the xml from virsh , edit it, undefine the current HostedEngine and define your modified HostedEngine 's  xml. Once you do that, you can try to start the VM. Good luck.

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.
