As of kernel 4.18 the virtio guest driver uses the SRIOV VF channel when it can or otherwise falls back to the classical the para-virtual channel. With this setup live-migration of VMs running under SRIOV is possible.

Or Gerlitz and Parav Pandit handle the v-switch host side of the equation for live-migration. They propose a design based on the switchdev mode for NIC host drivers.
