Re: [libvirt] [PATCH 0/6] Add usb controller model="none"

This series adds support for completely disabling USB bus for a host if a user requires this. For this to work a new USB controller model "none" was added that removes the USB bus. The controller is added in patches 2-4. Patch 1 cleans up some nits (and is not necessary) and patches 5 and 6 tweak qemuxml2argvtest and add tests to check the new controller.
