I'm following your instructions now to get a fresh Xen/ARM on my Cubie2
as well -- those are great notes!

Another thing worth trying is to bring up a FreeBSD/Xen/ARM guest on
your setup to check that it comes up with that version of Xen.  It looks
like we're heading towards FreeBSD being a potential replacement for
MiniOS as a bootloader in the longer term. Having the FreeBSD/Xen/ARM guest
working means that we could in theory unify the Raspberry Pi and Xen
Mirage backends.

See these about FreeBSD on Xen:

[+CC Julien] is your git tree still the best place to get a working copy
of FreeBSD/ARM/Xen, or has it been upstreamed elsewhere now?
