As far as i have played with Xen , You can dynamically allocate RAM to a running VM but the OS inside the VM is NOT able to detect the increased RAM and therefore cannot utilize it. If you reboot the VM , then on reboot it will show the increased memory. ( Conditions like max mem are assumend to be satified) If I'm not completely off here, Linux PVM domUs *do* see and utilize it.Adding memory is not a big problem, reducing the amount of memory is one. Just imagine a process using 500 megs and you take away 200 of that while it is running. If you have 200 megs of unused memory, this should work, though.
