Subject: [Virtio-fs] [PULL 05/18] remote/machine: add vfio-user property
Date: Wed, 15 Jun 2022 16:51:16 +0100	[thread overview]
Message-ID: <20220615155129.1025811-6-stefanha@redhat.com> (raw)
In-Reply-To: <20220615155129.1025811-1-stefanha@redhat.com>

From: Jagannathan Raman <jag.raman@oracle.com>

Add vfio-user to x-remote machine. It is a boolean, which indicates if
the machine supports vfio-user protocol. The machine configures the bus
differently vfio-user and multiprocess protocols, so this property
informs it on how to configure the bus.

This property should be short lived. Once vfio-user fully replaces
multiprocess, this property could be removed.
