Hello,
I'm importing a VM into a new oVirt environment that is in 4.3.10: the new
host is the same as the previous one (only difference it is in 4.3.10 while
the old one in 4.3.9).
This VM acted as a single host HCI environment (with 4.3.9). I imported the
storage domain containing the VM and its disks and the VM boots ok.
Now its Hosted Engine VM (that is so a nested VM) doesn't start.
I think it was good when I stopped/detached it... and so I would like to
cross check and verify if I missed something configuring the new
environment or something changed from 4.3.9 to 4.3.10
In vdsm.log I see this reason:
2020-07-23 14:38:20,489+0200 ERROR (vm/9233dc8b) [virt.vm]

The relevant parts of the generated xml in vdsm.log seems:

Any insights?
The configuration of the new 4.3.10 physical oVirt environment that
contains the VM has this cluster cpu type:
Intel Skylake Server IBRS SSBD MDS Family
Do I have to change it to anything else? I don't remember how it was set in
4.3.9
Thanks in advance,
Gianluca
