If you would edit /boot/extlinux.conf on the control domain you would
see, that the second menu entry (xe-serial) has a dom0_mem option. If
you use the standard (graphical) xe menu entry then you would need to
put a similar dom0_mem option in it. However you will need to reboot the
whole control domain for your changes to take effect.

Good Luck
