That particular error is about libvirt not setting up a correct PCI controller layout, however that's fixed in f26. The remaining 'bug' in this area is that the default added <video> device gets model=cirrus which isn't available for aarch64, so libvirt should default to a different model That said, your config as is isn't going to work at any point. For x86 VMs you can just add a <graphics> device and automatically and libvirt fills in the <video> config, and qemu gives an implicit mouse/keyboard setup. However on other archs you need to specify the mouse/keyboard manually On f26, you can define that XML, then open up virt-manager, and add a controller=usb3, input=tablet, input=usb keyboard, and change the video model to virtio and it should work patches posted upstream: https://www.redhat.com/archives/libvir-list/2017-June/msg01269.html Upstream now:
