[Libvir] [PATCH] Have xen fv acknowledge <boot> tag

[Cole Robinson <crobinso redhat com>]

https://bugzilla.redhat.com/show_bug.cgi?id=428868

Defining a xen fullvirt guest with a <boot dev="{hd,cdrom,etc.}"> 
tag currently ignores this tag and forces in a kernel tag.
Dan pointed out the fix in the bz, which I verified does the trick.

Patch attached.

Thanks,
Cole
