Can you be more specific about the failure scenarios?
Does this mean that migration cannot work today with guests using ipv6? I don't
think just pushing this to the guest is an acceptable solution in the short term.
Are there scenarios we cannot handle no matter what in the host? Does this mean
that for emulated drivers, we're completely out of luck?
