 PVE::Storage::volume_snapshot($storecfg, $volid, $snap) if storage_support_snapshop($volid, $storecfg); 
 return if !$running; 
 vm_mon_cmd($vmid, "snapshot-drive", device => $deviceid, name => $snap);

and
storage_support_snapshop {
...
 if ($volid =~ m/\.(qcow2|qed)$/){ 
+ $ret = 1; 
+ } 


So, with this code, we always call qemu-img snasphot for qcow2, which is wrong if the vm is running.
(for rbd,zfs,.. no problem).

I think that's why we passed the running flag to pve-storage.

Form what I see this case is already handled inside storage_support_snapshop()?
