Paul, your Reviewed-by: on this one is conspicuous in its absence. I
mentioned migration in the cover letter — this much is working fine,
but it's the PV back ends that don't yet work.

I'd quite like to merge the basic serialization/deserialization of
XenStore itself, with the unit tests.

Perhaps we can also set TYPE_XEN_DEVICE or TYPE_XEN_BLOCK_DEVICE to be
unmigratable? Ideally I think we want TYPE_XEN_DEVICE to be
unmigratable by default *unless* the specific device class (including
net and other as we port them from XenLegacyDevice) says otherwise.

Is there a way to do that?
