[ovirt-users] Disk's locked of VM

Thu Jul 10 05:57:48 UTC 2014

Hello Vered,

Sorry for the late reply. You did more than try. With your help I resolved
my problem.

I was busy doing my job. This is only a side thing according to my boss but
he doesn't know how much time we will safe if we have a decent and easy to
use test enviroment to see why something happen in the real world at our
customers.

But anyways ...

I have the following setup. One server with the engine on and this one also
delivers the storage via nfs.
On another server I have only the VDSM setup.

When I say I'm trying to put the disk in stateless mode (off a VM machine)
I' mean that I'm trying to install new software on a VM but when I reboot
everything is back the way it was before the changed situation of the new
software.

Kind regards.
