There is no built in mechanism for this, mostly to make sure you aren't overcommitting the total memory you have in the system. If you want this kind of functionality you would have to build a script which monitors memory usage on each VM and uses the mem-set command to adjust as necessary. But that would be fairly tricky.

I see this feature in other virtualization systems, but can't find any mention

Can Xen give a guaranteed minimum amount of ram to a VM, but allow it to take
more to a certain limit if required?
The VMs certainly handle having the amount of memory they have changed
manually with "xm mem-set", so doesn't seem so far fetched an idea.
Thanks
