Hi Robert,

If I understand correctly you are trying to share disks between two VMs,
In Ovirt you can set a disk as sharable by editing the disk properties.
A shareable disk can be attached to multiple VMs.

If you wish to detach a disk from one VM and attach it to another VM it is
simple too,
select the VM that hold the relevant disk and detach the disk from it, you
will find the detached disk under the 'disks' tab.
To attach the floating disk to another VM, select the desired VM, go to the
disks tab and press 'attach'.
You will see all the floating disks that exist in the data-center.

I hope it helped, please ask if you have more questions.
