Well, migration could be partly implemented using process checkpointing.
I guess what is missing in DragonFly's process checkpointing is
remembering the state of the associated files/sockets. Thinking about
it, in the case of a vkernel, this should be no big deal. Anyone ever
tried to checkpoint a running vkernel?

That would be pretty cool to just checkpoint a running vkernel and
reload it on any other machine (with a somewhat similar configuration).
But I'm really missing a use case for myself right now ;-)
