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.
