'unknown' means the host is in non-responsive state.
the "correct" approach is to correct the status of the host (stop via 
the power management options ('fence'), or 'confirm manual shutdown' of 
the host.
either should release the 'unknown' status of the VM.

for extreme cases (aka 'bugs'), there is a command line unlock utility 
to be used with caution.
