Commit a9994687cb9b ("vfio/display: core & wireup") added display
169b9a
support to vfio-pci with the default being "auto", which breaks
169b9a
existing VMs when the vGPU requires GL support but had no previous
169b9a
requirement for a GL compatible configuration.  "Off" is the safer
169b9a
default as we impose no new requirements to VM configurations.
