Try to remove all the USB controllers and libvirt will still let you define the domain, which is wrong given the USB based tablet for mouse input. When you try to start the domain it will fail with the following: qemu-system-x86_64: -device usb-tablet,id=input0: No 'usb-bus' bus found for device 'usb-tablet' So we obviously need to ensure there is a USB controller defined and stop relying on the implicit one but that's outside of the scope of q35 work since technically this affects i440fx as well. -- Doug Goldstein -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
