I have xen-2.0.1 in a PentiumIII with 131079 kb of RAM, I configed my system by following the suggestions.
When I boot xen0, the following error msg printed on the screen:

(xen) not enough memory for DOM0 memory reservation


My grub configuration look like this:

title Xen 2.0.1 / XenLinux 2.6.9
     kernel /boot/xen.gz dom0_mem=131072 console=vga

It seems like you're trying to use the entire physical memory for domain0. But the hypervisor needs some memory of it's own (32MB, IIRC). Try reducing dom0_mem to (phys_mem-32MB) or so?
