From 73bc4f185e314e9738125993b5a72585ea3c42c4 Mon Sep 17 00:00:00 2001 From: Andrea Bolognani Date: Wed, 6 Mar 2019 12:10:05 +0100 Subject: [PATCH] docs: Document configuration quirks for virtio devices Some devices (namely virtio-scsi, virtio-gpu, virtio-keyboard, virtio-tablet and virtio-mouse, plus virtio-crypto which is not supported by libvirt) don't follow the same rules as all other virtio devices, which is something that ought to be documented.

+ While the information outlined above applies to most virtio devices, + there are a few exceptions: +

+ +
    +
  • + for SCSI controllers, virtio-scsi must be used instead + of virtio for backwards compatibility reasons; +
    • +
  • + some devices, such as GPUs and input devices (keyboard, tablet and + mouse), are only defined in the virtio 1.0 spec and as such don't + have a transitional variant: the only accepted model is + virtio, which will result in a non-transitional device. +
