virtio spec requires drivers to set DRIVER_OK before using VQs. This is set automatically after resume returns, virtio balloon violated this rule by adding bufs, which causes the VQ to be used directly within restore. To fix, call virtio_enable_vqs_early before using VQ. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> --- drivers/virtio/virtio_balloon.c | 2 ++ 1 file changed, 2 insertions(+)
