Re: [libvirt-users] libvirt and virt-manager - Unable to complete install: 'internal error: unsupported input bus usb'

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):   File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper     callback(asyncjob, *args, **kwargs)   File "/usr/share/virt-manager/virtManager/create.py", line 2276, in _do_async_install     guest.start_install(meter=meter)   File "/usr/share/virt-manager/virtinst/guest.py", line 461, in start_install     doboot, transient)   File "/usr/share/virt-manager/virtinst/guest.py", line 397, in _create_guest     domain = self.conn.createXML(install_xml or final_xml, 0)   File "/usr/lib/python3.7/site-packages/libvirt.py", line 3717, in createXML     if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) 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 .
