I don't have experience in libvirt and I don't use it on xen server.
I'm trying to improve xen hvm domUs performance and features (not only 
for hvm) even if probably I don't have enoght knowledge and time to do 
everything :(
I used libvirt only in fast kvm tests and I saw that with kvm have 
already support for spice usbredir, image compression and streaming 
options but I probably not able to implement the same options for xen 
too fast and in a good and complete way.
