1. Transfer configuration data. Currently there is no VM configuration data transferred with the stream. One has to start QEMU/KVM with the _exact_ same parameters on the other side to allow migration. If there would be a pseudo-device (transferred first) holding these parameters (and other runtime dependent stuff like kvm_enabled()) this would ease migration a lot.

I presently have code which *relies* on the ability to migrate from one VM to a target with different different backing stores for their disk images (albeit sharing the same contents).

If this ability were to be removed, that would be unfortunate.
