I have a VirtualBox VM (with Windows Server 2012 as both host and guest). I created several snapshots while configuring some difficult stuff:
Before installing OS
\____ Before installing software A
\____ Before installing software B
\____ Before installing software C
\____ Testing this
\____ Testing that
\____ Current state
Now everything works and I need the disk space so I want to discard all snapshots. My research suggests that there's no other way to remove snapshots than one by one, painfully slow as it is. I can't clone or export the VM because it's already using 75% of the host disk.
Should I start removing from top to bottom or viceversa? What would result in faster merges? Or it doesn't really matter?
