I think that's what xen was asking you. It was just that in the default setup, it wants to know what your VM should have when you start xen. When xen isn't running, it shouldn't take any RAM. You can always setup Xen, then do a free -lm
and look at the -/+ buffers/cache: line. The used and free should add up to 1GB (roughly) for you when Xen isn't running.
I did upgrade my RAM to 2GB though because with 1GB it was a little rough running XP and linux...
