Description
After a number of rollbacks to a certain live snapshot the guest (Ubuntu Server 16.04) seems to restore its state but becomes totally unresponsive. It just hangs on the prompt, the video doesn't change at all (even the cursor doesn't blink), and pressing any keyboard keys doesn't have any effect. Htop also shows that one of the cores is loaded 100% with the VBoxHeadless process. You may reboot the guest forcefully and it starts just fine. It's just I have to do a lot of rollbacks to live snapshots automatically that this occasional freeze bugs me big time.
P.S. If that makes any difference - I'm doing headless start instead of normal start
P.S.S. Bug seems to be very occasional - once in a few dozen times maybe
