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.. :) Dave --=20 David Muench - davemuench@gmail.com Jabber ID: dave@jabber.wasteland.org
