Because a clean shutdown of the VMs is more important than high uptime
for the VMs.

If both guest and host machines shut down at the same time, the host
might finish its shutdown before the guests have, leading to possible
filesystem corruption. I will gladly trade off some downtime of the VMs
to ensure clean shutdowns.

Thanks -- that's what I'm asking for -- what is it that I configure, and
 are there sample configs someplace that do this?

thanks again
