+
+Commit 9b3a35ec82 ("virtio: verify that legacy support is not
+accidentally on") added a safety check that requires to set
+'disable-legacy=on' on vhost-user-vsock-pci device:
+
+    $ ./qemu-system-x86_64 ... \
+    -chardev socket,id=char0,reconnect=0,path=/tmp/vhost4.socket \
+    -device vhost-user-vsock-pci,chardev=char0
+        qemu-system-x86_64: -device vhost-user-vsock-pci,chardev=char0:
+        device is modern-only, use disable-legacy=on
+
+virtio-vsock was introduced after the release of VIRTIO 1.0
+specifications, so it should be 'modern-only'.
+
+This patch forces virtio version 1 and removes the 'transitional_name'
+property, as done for vhost-vsock-pci, removing the need to specify
+'disable-legacy=on' on vhost-user-vsock-pci device.

+        device is modern-only, use disable-legacy=on
+
+virtio-vsock was introduced after the release of VIRTIO 1.0
+specifications, so it should be 'modern-only'.
+In addition Cornelia verified that forcing a legacy mode on
+vhost-vsock-pci device using x86-64 host and s390x guest, so with
+different endianness, produces strange behaviours.
+
+This patch forces virtio version 1 and removes the 'transitional_name'
+property removing the need to specify 'disable-legacy=on' on
+vhost-vsock-pci device.
+
+To avoid migration issues, we force virtio version 1 only when
+legacy check is enabled in the new machine types (>= 5.1).
+
+As the transitional device name is not commonly used, we do not
+provide compatibility handling for it.

+Commit 9b3a35ec82 ("virtio: verify that legacy support is not accidentally
+on") added a check that returns an error if legacy support is on, but the
+device does not support legacy.
+
+Unfortunately some devices were wrongly declared legacy capable even if
+they were not (e.g vhost-vsock).
+
+To avoid migration issues, we add a virtio-device property
+(x-disable-legacy-check) to skip the legacy error, printing a warning
+instead, for machine types < 5.1.
