In fact I think we want to only serialize the contents of the domain's
path in /local/domain/${domid} and leave the rest to be recreated? Will
defer to Paul for that.

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.
The patch is basically ok, I just think the serialization should be
limited to the guest nodes... filtering out those not owned by xen_domid
would probably work for that.
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.
Yes, that sounds like a good idea.
Is there a way to do that?
Not something I've looked into. I'll go look now.
