Re: [Xen-devel] A migration framework for external devices

To be a bit clearer on the idea of the framework: It would consist of

to de-serialize them (which mere 'scp' would not do).
So an underlying assumption would be that the local and remove real or
virtual devices support serialize/deserialize of state, correct?

Yes, that's correct.

Would also be very cool if the framework had pre-migration hooks. For example, allow someone to write a plugin to verify that the target host is qualified and in a good state to accept a migration before it actually starts.

Also, some physical devices may need to be configured/re-configured on the target prior to a migration (infiniband, fiber channel, iscsi) and it would be good to have plugins for that as well.
