Do you use Xen for Virtualization?

If you use Xen, what type of guests do you typically run?
Paravirtualized (pv)
Fully Virtualized (hvm)
PVH

Do you manage Xen guests with the libvirt toolstack (virsh,
virt-manager, virt-install)?

Do you manage Xen guests with the libxl toolstack (xl )?

Thanks

I use Xen extensively. Paravirualized. LibXL. I run 15.6 guests on 15.6 hosts. Works fantastic.
