[libvirt] VN-Link vNIC memory state copying on VM Migration

[Jagath Weerasinghe]

Chris,

Thanks for the reply.

>  what memory state do you refer to exactly?
What I meant by the memory state is the traffic being
transferred through the vNIC when VM migration is triggered.

If this memory state (or traffic) is not copied and moved to the
destination vNIC how the smooth communication, which is
guaranteed on VM migration, is achieved?

Thanks
Jagath
