[Dong, Eddie] Hi Jason:
        How about we take staging approach? In general, COLO opens a door of 
high performance HA solution, but it will take very long time to make 
everything perfect. As for the network virtualization, I think we may start 
from usage with moderate network bandwidth, like 1Gbps. Otherwise, the 
performance of COLO may be not that good (of course, like David mentioned, the 
worst case is same with periodic checkpoint). At the moment, how about we start 
from in Qemu virtio network, and enhance for vhost case in future? 

        The good thing is that we get more people working on the patch series, 
and glad to see UMU also joined the effort.  Thanks and welcome...

Thx Eddie
