I'm trying create a virtual machine using Xen as hypervisor and virt-manager (libvirt) as the management module. When trying to create the virtual machine I am getting the following error:

"

Unable to complete install: 'internal error: unsupported input bus usb'

"

ERROR DETAILS:

Unable to complete install: 'internal error: unsupported input bus usb'

Traceback (most recent call last):

libvirt.libvirtError: internal error: unsupported input bus usb

NOTE I: The deploy process follows the instructions here https://www.youtube.com/watch?v=BwkmDM-Gpzc and here https://wiki.centos.org/HowTos/Xen/Xen4QuickStart .

NOTE II: Xen Hypervisor uses a CentOS 7 as "domu".
