From 27eda699f59d430c33fc054a36a17251992e70dc Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Mon, 21 Sep 2020 14:25:05 +0200 Subject: [PATCH] vhost-user-vsock-pci: force virtio version 1 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.
