[PULL v4 19/48] vhost-vsock-ccw: force virtio version 1 |
Date: |

From: Stefano Garzarella <sgarzare@redhat.com>
virtio-vsock was introduced after the release of VIRTIO 1.0
specifications, so it should be 'modern-only'.
This patch forces virtio version 1 as done for vhost-vsock-pci.
To avoid migration issues, we force virtio version 1 only when
legacy check is enabled in the new machine types (>= 5.1).
