Re: [libvirt] [PATCHv3 0/3] 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. This series incorporates fixes for comments of Dan's and Eric's review and is rebased on top of Dan's error handling cleanup.
