Dual boot will be the best choice... ;-)
You can even share the same /boot for both root file systems, for example:

/dev/sda1 on /boot 256M (Two options in GRUB, one for each root file system)
/dev/sda2 on / 10G (For Xen 3.3.1)
/dev/sda3 on / 10G (For Xen-unstable)

It's not easy.
Although you can (at least on Linux) mix-and-match dom0 kernel, the
hypervisor is tightly connected to userland programs (xend, xm, etc.).
Having two hypervisors is easy, but having both version of userland
programs is hard since (by default) it's installed in the same
location with the same name.

Since you can't activate both at the same time anyway, my suggestion
is to have separate root partition/LV for each version. Kinda like
dual boot.
