I've installed Xen Hypervisor 3.0.3 (CentOS 5.7, i386) inside Virtualbox 4.1.16 (Mageia 1, i686) and have noticed that Dom0 is consuming 85% of the memory allocated to the VM (1GB) so I'd like to reduce this as much as possible in order to make more room for one or two VM's.

Is there a minimum amount of vRAM that can/should be allocated to Dom0 (using the dom0_mem boot parameter) considering that I only want to host one or two VM's?
