Last weekend I took another wag at this, and discovered if I
used the libxl interfaces in libvirt, I could get it to build
easily, and fairly quickly.

I'm now going through the package, and trying to add support for
a couple of the storage drivers (as options) that it seems
NetBSD could easily support.  I hope to be checking the changes
in over the upcomming weekend.

One note, currently only xentools42 provides the needed
libraries and include files required for libvirt to build.  So,
libvirt currently requires xentools42 when the "xen" option is
selected.

If someone wants to take a wag at exporting more of the include
files and libraries in xen41, it could be supported too..
(actually, any xen release that provides a libxl and associated
include files should be possible to support.)
