Something similar here: AMD64 with 4GB RAM running a 64-bit Gentoo Dom0,
running 30 DomUs, which are mixed 32-bit Debian/SuSE/FC4/CentOS and 64-bit
Gentoo, but all with a 64-bit kernel for the DomU. If you don't choose stupid
compiler-settings (beware of -Os, it creates broken code), it's running very,
very smoothly.

One question I've been meaning to ask, and I haven't had the time to check myself is if there are problems when using a  64bit domU kernel with modules and 32bit userland modutils in Debian or other distributions.

Does a 32bit userland imply the need for static non-module kernels?
