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