I didn't see any point.  I figured swap for a guest would be one of the 
more expensive issues (performance wise).  As I don't seem to be 
consuming the system memory available - it looks like a non-issue to 
me.  I would think (and as usual I'm probably wrong) the only reason I'd 
enable swap in the guest would be to reduce the "locked" memory load on 
the host.  Right now with 16G on the host server, I've got about 4G free 
and 5G in cache - so I think my memory settings are reasonable.

Unless there's a particular reason to allocate more memory to any of my 
guests or conserve more for the host.
