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

Hello, I did something like that via "virsh edit HostedEngine". But how is the change written back to the shared storage ("hosted_storage" so it stays permanent  for HA Engine ? I was able to boot up HostedEngine manually via virsh start after removing the required flag from XML (I first added a user to sasldb in /etc/libvirt/passwd.db to be able to log into libvirt).

Once you do that, you can try to start the VM. Good luck.
