I'm starting a business on a shoestring budget so even extra RAM is
expensive. 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...

Ever lied? You're a liar. Ever stolen? You're a thief. Ever hated? The
bible equates hate with murder. Ever lusted? Jesus equated lust with
adultery. You've broken God's law.
He'll judge all evil and you're without hope -- unless you have a savior.
Repent and believe.
