I'm not sure about PCI pass-through support, but the network acceleration plugin architecture we contributed to 3.2 makes solving the problems of save/restore and migration between servers (even with different hardware) much easier for those things that use it. Migration using PCI pass-through will be tricky to say the least, even between identical hardware, and particularly if you have any state on your NIC.
