Definitely self-contained guests. That way :
- you can easily migrate domUs without having to worry what kernel is
available on dom0. For example, migrating from Linux dom0 to
Opensolaris dom0.
- When setup correctly, you have the possibility to use the same image
for both PV and HVM domU.

Yes :
- make sure a kernel-xen (or similar) package is installed on domU
- setup initrd and grub.conf on domU correctly
- modify domU xen config to use a bootloader (e.g. pygrub) instead of
a kernel and initrd
