I left memtest86 running for 2 days and no error detected :(

Yep, it happens only for the 96GB VM. Other VMs with fewer RAM (16GB for
example) can be created on or migrated to that host flawlessly. I'll try to
play a little with BIOS settings but otherwise I'll have the HW replaced. I
was only trying to rule out possible oVirt SW problems due to that host
being the first I deployed (from CLI) when I installed the cluster.

Thanks!
