For tap and vhost kernel, no special kernel features are required. But in addition
to these cpr-transfer patches, you will need the "Live Update: tap and vhost" RFC
V1 that I posted, and it might not apply cleanly to this most recent cpr-transfer
series. I will eventually update that series, but not immediately.
Also, I have never tried vhost-user, so not sure it will work without additional
changes in qemu.
