Hi,
It is located on NFS storage domain V4.
Note that there is a bug that will prevent you from creating a VM from a
template as with preallocated disks -
https://bugzilla.redhat.com/show_bug.cgi?id=1403183
This was fixed only in version 4.3
Furthermore, it seems that fix missed the scenario you described.
Can you please submit a bug and attach the VDSM and the engine logs?
