So... what would you expect service down wise for the following
solution which is zero touch and I think should work for any VF
driver:
on host A: unplug the VM and conduct live migration to host B ala the
no-SRIOV case.
on host B:
when the VM "gets back to live", probe a VF there with the same assigned mac
next, udev on the VM will call the VF driver to create netdev instance
DHCP client would run to get the same IP address
+ under config directive (or from Qemu) send Gratuitous ARP to notify
the switch/es on the new location for that mac.
Or.
