From edc91b968fea48d5c7141c3fd21ba6a89b6c2369 Mon Sep 17 00:00:00 2001 Message-Id: From: Erik Skultety Date: Thu, 19 Jul 2018 15:04:03 +0200 Subject: [PATCH] qemu: command: Enable formatting vfio-pci.display option onto cmdline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since QEMU 2.12, QEMU understands a new vfio-pci device option 'display' which can be used to turn on display capabilities on vgpu-enabled mediated devices, IOW emulated GPU devices like QXL will no longer be needed with vgpu-enable mdevs. QEMU defaults to 'auto' for the 'display' attribute, which is not foolproof, so we need to play it safe here and default to display='off' if this attribute wasn't provided in the XML explicitly.
