A VM is like a true OS in this respect, so no, if the system hangs there
is no way to recover the data, that is, you have to perform a "hard
reset" by shutting down or resetting the machine. The same remains true
for standard (real) installations.
What you have to do is debugging the system "lock/freeze" the same way
you would do with a real system.
Tips:
1/ Can you ssh into the VM when is locked? Maybe is X what freezes and
not the kernel.
2/ Do you have any interesting information about the lock in the logs?
3/ VirtualBox tends to "pause" the VM and you have to manually put into
"play" again. I think it pauses the machine because it has low resources
available. Check the host specs and guest VM settings for system and
video RAM.
