Hi,
the host and VM are all up-to-date with latest packages for CentOS 7.*.
In /proc/cpuinfo I see "nx" in the flags list, the full list is on the
and of the mail.
Is it possible that this problem destroy the Windows Server 2012 R2 VM?
Now I start the third installation, hopefully this time it will not get
damaged. If it fails again I have to use another virtualization provider
and leave oVirt, and I was so happy to leave VMWare :°(
This is the command line for a VM (got with ps aux ...):
