In which case, wouldn't it just be a whole lot simpler to have qemu-dm
know about these constants and just have a configuration parameter to
cause it to serve up the right one when asked? 

We probably should have a 'guest_type' field in the guest config anyway
as we'll likely want to use this for enabling/tuning various
optimizations.

I know this isn't ideal from a purist virtualization point of view, but
it seems like a practical solution.

We'll have to think about how this data gets persisted (I'd trigger a
watcher and store it outside of xenstore). Look at the xen-api.hg tree
to see how stuff gets persisted.
