Change subject: core: Allow creation of new disks as copy of any existing disk
......................................................................


Patch Set 4:

> Hi Tomas, thanks for the fixes.
> Few questions though, not that we allow copy of disk from a VM, how should we 
> handle:
> 1) shared disk - I assume it will have the same behviour as before
It will just create a new disk which will also be sharable. Do you mean that it 
should be disallowed to copy the sharable disk to glusterfs?

> 2) External LUN disk - should we blocked that one?
The MoveOrCopyDiskCommand works only with images

> 3) OVF_STORE disk
Not supported - checked in canDoAction() -> isDiskUsedAsOvfStore()

> Also how a disk with snapshots should be copied? If a disk contains snapshots 
> I guess it will be copied with collapse snapshots (Am I wrong?)
yes, in overrideParameters() there is this call: 
getParameters().setUseCopyCollapse(true); so the VDS command which causes the 
collapse copy will be called
