Timofey has posted a patch which aims to improve shared storage negotiation
a little:


I've been thinking for some time about going bigger. It occurs to me that
the destination node has enough context to know what should be present. I
think it would be cleaner for the destination to check what it has, and
send the delta back to the source in migration_data. I think that would
remove the need for shared storage negotiation entirely. Of course, we'd
need to be careful about cleaning up after ourselves, but that's already
