on Ubuntu, XEN is set up as default already

on Debian, this might be required (setting up a higher boot priority for XEN)
#dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen update-grub
casual serial console will be gone and will become hvc0
systemctl disable serial-getty@ttyS0

and disable save/restore, which breaks NetBSD guests
