No problem, thanks very much for all your help. It still amazes me
that a Celeron in my basement can have 2 domains running web servers,
1 doing dns/dhcp/tftp type services, a mysql domain, a domain running
Asterisk to control all my VOIP phones, and a mythtv backend domain
that can simultaneously record 3 DVD quality mpeg-2 streams off of
directv while playing back to (at least) two frontend machines in my
house. All thanks to Xen. And I still have another 200 meg of
unallocated ram, I wonder what I can do with that.. :)
