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' "

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".

commit b1eb07c26aae1b303cd9893427f46f5b693544b3 (HEAD -> master, origin/master, origin/HEAD) Author: Cole Robinson <crobinso@redhat.com> Date: Wed Aug 22 08:38:33 2018 -0400 guest: Don't add usb tablet for xen PV xen PV doesn't have USB support But you can work around it: at the end of the 'new vm' wizard, click 'customize before install', and in the VM details window, remove the tablet device, then finish the install. That should make things work - Cole
