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".

Coincidentally this a bug I fixed just this morning:
commit b1eb07c26aae1b303cd9893427f46f5b693544b3 (HEAD -> master,
origin/master, origin/HEAD)

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
