[pve-devel] bug ? vmstate state snapshot file not closed on cancel

[Alexandre DERUMIER]

I have notice with rbd, that if we cancel a running snapshot with vmstate,
It seem that the vmstate file is not closed,
so we can't remove it with rbd.
(Not sure about the behaviour without other storage, but it seem to be wrong anyway)

I have check inside internal-snapshot-async.patch, I don't see any bdrv_close anywhere





#qm snapshot 100 snap1 --vmstate
