I was getting memory errors with 32 and 64 MB for domain 0 so I bumped it to 128. Seems like alot; I wasn''t aware domain0 needed so much. What are the rules of thumb? For about 10 32MB guests, how much RAM should domain0 need?

What were the errors? I know on CentOS(RHEL) it will warn you that it will not run as a "supported" configuration without 256M ram, this doesnt mean it won''t run on less though. In general I run my dom0 on about 128-256M. 128M is not really all that much these days. If you are thinking of running 32meg domU''s you may want to go with a minimal linux distro. but I think the 128M ram on your dom0 is a worthwhile investment for stabilty if nothing else.

Domain0 is on a minimal distro -- Debian 3.1r0a base install with no extra unnecessary packages and all unnecessary services disabled. At boot it uses 4MB RAM! And I was only running a copy of Domain0 in a guest domain when I started getting memory errors. Because of that, 128MB seems a bit much for one trimmed-down guest domain. Hence the question: what are Xen''s domain0 memory requirements? I don''t see them in the documentation... CD Ever lied? You''re a liar. Ever stolen? You''re a thief. Ever hated?
