Stefan Hajnoczi	6793dfd1b6	virtio: clear signalled_used_valid when switching from dataplane ... When the dataplane thread stops, its vring.c implementation synchronizes vring state back to virtio.c so we can continue emulating the virtio device. This patch ensures that virtio.c's signalled_used_valid flag is reset so that we do not suppress guest notifications due to stale signalled_used values.

Stefan Hajnoczi	9154b02c53	dataplane: sync virtio.c and vring.c virtqueue state ... Load the virtio.c state into vring.c when we start dataplane mode and vice versa when stopping dataplane mode. This patch makes it possible to start and stop dataplane any time while the guest is running. This will eventually allow us to go back to QEMU main loop for bdrv_drain_all() and live migration. In the meantime, this patch makes the dataplane lifecycle more robust but should make no visible difference. It may be useful in the virtio-net dataplane effort.
