Heres what happened.

I had a snapshot on which I was working from within a linux VM. A friend requested a clean VM as a clone of mine. So I closed / shutdown my running VM, made a copy of the Disk1.vdi along with the snapshots ({uuid}.vdi). Then I restarted the VM and did merged snapshots, deleted my home directory and made a tar+bz2 for my friend.

Then after I restored my backups, I am not able to mount my snapshot. The VM seems to boot from my version before snapshot. I cant seem to find a way to mount back my snapshot.

Any idea how to make VirtualBox see the snapshot and mount it?
