osstest looks perfect for what we need, especially if it could be
run regularly against released versions of Xen as well as xen-unstable.

Building them from scratch is probably best.  This just needs any version
of OCaml from 3.12.1 onwards, and we can provide a script that installs
the OPAM source manager, builds the kernel in question, and cleans itself
up (no root needed).

The best candidate to kick this off is probably the new OXenstored that
Dave Scott is working on, which adds support for a Git backend and will
probably have a few regressions due to rewritten transaction logic.
He's currently on the road, so some delay expected in reply.

cheers! I'll see if I can find a spare test machine in the Computer Lab
to set this up on too.   Thomas Leonard (CCed) has also just started
work on the Mirage/Xen/ARM backend, so it would be useful to have that
in the rotation eventually as well.
