Thanks for your info.
I checked SPICE and apparently is for HVM guest only, I'm using a PV-guest.

PVUSB is broken since 4.4;
quote: 'As of Xen 4.4 PVUSB is only supported with xm/xend toolstack.'
http://wiki.xenproject.org/wiki/Xen_USB_Passthrough#PVUSB_in_xl.2Flibxl
...and xm/xend does not go together with libvirt/xl-tools.
