Virt machine in qemu since v2.3.0 has PCI generic host controller, and can use PCI devices. This provides performance improvement as well as vhost-net with irqfd support for virtio-net. However libvirt still insists on virtio devices attached to virt machine to have MMIO bindings. This patch allows to use both. If the user doesn't specify <address type='virtio-mmio'>, PCI will be used by default.
Changes since v1: - Added capability based on qemu version number - Recognize also "virt-" prefix
Pavel Fedin (2): Introduce QEMU_CAPS_ARM_VIRT_PCI Allow PCI virtio on ARM "virt" machine
