File virtio-update-queue-size-on-guest-write.patch of Package qemu
From: "Michael S. Tsirkin" <mst@redhat.com> Date: Fri, 13 Dec 2019 09:22:48 -0500 Subject: virtio: update queue size on guest write Git-commit: d0c5f643383b9e84316f148affff368ac33d75b9 Some guests read back queue size after writing it. Update the size immediatly upon write otherwise they get confused. In particular this is the case for seabios.
