From what i read in this thread, i believe to understand that snapshots could be taken from a VM on a LVM-thin storage in raw format. However, the moment i pass through disks, this breaks the ability to take snapshots. Did I get this right?
If so, is there a way to tell the snapshot mechanism to just ignore the passtrough disks? In my case, they are just media storages not related to the OS in the guest system (meaing the guest system runs perfectly fine without these passgtroughs).
If there's not, would the solution be to create a script, unmount the passtroughs, snapshot, remount? Or would there sill be something blocking it?
