I am running VirtualBox 4.3.0 on OS X 10.9, and I somehow got my Ubuntu Server 13.10 VM into an aborted state. Now I can't do anything about it;
controlvm poweroff, or whatever all fail to work. To make things worse, I don't have any snapshots. In this case, is it possible to recover the vm? I've googled for a solution but surprisingly I didn't find anything.
If you are certain that no solution exists, please also leave a comment/answer. Thanks.
Feeling doubtful about the chances of recovery, I deleted the VM and started from scratch. This VM was rather new (built after 13.10 release), so hopefully configuring a new one to normal working state won't consume too much time.
Therefore, I won't be able to test any suggested solutions. Anyway, comments and answers are still welcome, as they may benefit future users with this problem.
