There is memory hotplug mechanism (only for Linux now) under
development. I think that solution allow you to expand memory
guest above limit declared at system startup (if you underestimated
it at that stage).
Feel free to test it:
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git,
xen/memory-hotplug head.
If you have any questions please drop me a line.
