[one-users] Cannot clone persistent image

Wed May 1 02:43:57 PDT 2013

Now your error may be other:

"Mon Apr 29 12:43:14 2013 [VMM][I]: error: internal error process exited
while connecting to monitor: Could not access KVM kernel module: Permission
denied"

Sometimes is needed for oneadmin to be part of the kvm group to access
/dev/kvm...

Cheers

Ruben
