[Qemu-devel] [PATCH 90/99] vfio/pci: Default display option to "off"

From: Michael Roth
Subject: [Qemu-devel] [PATCH 90/99] vfio/pci: Default display option to "off"
Date: Mon, 23 Jul 2018 15:17:39 -0500

From: Alex Williamson <address@hidden>

Commit a9994687cb9b ("vfio/display: core & wireup") added display
support to vfio-pci with the default being "auto", which breaks
existing VMs when the vGPU requires GL support but had no previous
requirement for a GL compatible configuration.  "Off" is the safer
default as we impose no new requirements to VM configurations.

Fixes: a9994687cb9b ("vfio/display: core & wireup")
