what do you mean by snapshot used by another snapshot?
ex:
image->snap1-snap2->you are here

you can delete snap1 without any problem, and without need to merge. 

the only thing with zfs, is that you can't rollback to snap1 without deleting 
snap2.

Yes, something like that.

Ah, good to know. Besides, connecting with ssh looks still strange to me. 

But I guess we will only backup VM without snapshots, so we do not 
need that for backup purposes. 

BTW, is there really no way to delete nexenta snapshots used by another 
snapshot (snapshot merge)? If not, should we implement that on the qemu side?
