Re: [libvirt] [PATCH v2] qemu: Use virtio network device for aarch64/virt

This patch changes network device type used by default from rtl8139 to virtio when architecture type is aarch64 and machine type is virt. Qemu doesn't support any other machine types for aarch64 right now and we can't make any other aarch64-specific tuning in this function yet. Signed-off-by: Oleg Strikov <oleg.strikov(a)canonical.com&gt; --- Changes since v1: * qemuxml2argvtest suite has been extended to validate correct setup for aarch64 guests when no NIC model is provided in the XML
