Okay, one thing I've noticed, my NetBSD domU never seems to 'idle' from 
the hypervisor's perspective.  Check out the domain list:

root@rackable:/etc/xen# xm vcpu-list

The 'time' column for the NetBSD domain counts up every second even 
though 'top' in netbsd-51 shows both CPU's as 100% idle.  Basically, 
what you are seeing is a timer of how long the domain has been running 
since I created it.

I don't know what this means, but I report it because it seems to be 
different from all the other OS in the list.
