Currently, MAC registration occurs during device creation, which is early enough that, during live migration, you end up with duplicate MAC addresses on still-running source and target devices, even though the target device isn't actually being used yet. This patch proposes to defer MAC registration until right before the guest can actually use the device -- In other words, right before starting guest CPUs.
