Marcel Apfelbaum 2016-09-29 13:15:26 UTC Doc Text Cause:
On Q35 the virtio devices connected to PCIe Root Ports or PCIe Downstream Ports are virtio 1.0 with no legacy support by default as opposed to previous versions.

Consequence:
Existing Windows guests having the system storage device a virtio device connected to PCIe Root Ports or PCIe Downstream Ports will not boot anymore after upgrade.

Workaround:
Add a second virtio non-boot disk with "disable-legacy=on", install a driver for the controller, reboot and then remove it.

Result:
Windows will load the right driver for the virtio boot disk and the system will boot successfully.
