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?
Yes, of course and it makes sense.
Mentioning vhost here is to avoid re-inventing or abandoning some exist
infrastructures. For example, thinking how netfiler can work with vhost
from the beginning does not harm ...
