You need to restart XenD (or reboot the host). We didn't automatically resart
XenD in the %post script because that doesn't play nicely if you have any
fullvirt guests running :-(

Its a new function actually - previous 'xm list' just reported what you'd
told XenD to give the guest - this was not the same as what the guest was
actually allocated by the  HV. The new getSysMem function is used to make
xm list show the correct (actual) allocation
