I'm experimenting with Gerd's excellent work on integrating Xenner
into Qemu (http://git.et.redhat.com/?p=qemu-kraxel.git). I'm using it
to boot a FreeBSD guest that uses the Xen paravirtual network drivers.
Decoupling the Xen PV guest support from the hypervisor really
simplifies deployment.

v3: separate blob_{addr,size}_{32,64}; move xen_hvm_config to struct
