It might be really useful to change the display behavior to be much more
like what is returned with 'ps' for processes, with additional Xen states. 
The 5 colums that never seem to show more than 1 at once (though it is
possible) seems very odd from an interface perspective.

Possible States (using PS states when appropriate)

R - running
B - blocked
P - paused
C - crashed
S - sleeping
H - halted (aka stopped)

As with ps you could have multiple state flags set (like SN), so getting rid
of the 5 columns wouldn't limit your options.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
