Thanks guys,

Your questions lead me to the fact that another technician had
installed "vdsm-hook-nestedvt" to try and get nested virtualization on
a VM working a while back. I have removed the hook and restarted and
this resolved the issue.

Thanks once again, much appreciated.

Regards.

Neil Wilson.
