From 9a4c0e220d8a4f82b5665d0ee95ef94d8e1509d5 Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Wed, 20 Jul 2016 18:28:21 +0300 Subject: hw/virtio-pci: fix virtio behaviour Enable transitional virtio devices by default. Enable virtio-1.0 for devices plugged into PCIe ports (Root ports or Downstream ports). Using the virtio-1 mode will remove the limitation of the number of devices that can be attached to a machine by removing the need for the IO BAR.
