  Hum, this really is the installation of Xen, hopefully you should be able
to download prepackaged version, including the development part to avoid this,
but I have no experience with Debian myself.

  That is the standard process, but again using prepackaged versions
would be nicer. Also note that theorically libvirt should now be able
to compile and work without Xen support assuming QEmu (and possibly KVM
support in recent kernel versions).

  I would also make sure the http server is desactivated this is a giant
security hole:

  Ideally we should find prepackaged version for most common OS, coming with
the OS or from trusted sources. I'm fine pointing to such repositories, and
providing instructions on how to install in the FAQ. And if the problem
is storage, I'm fine hosting packages on libvirt.org itself, I just need
a person willing to maintain the package for one year at least (i.e. providing
updates).
  And as usual if there is portability problems and/or fixes, send them
to the list, I'm eager to get libvirt on new platform, new oses, and new
virtualization engines ! 
  For example I'm wondering about -fno-stack-protector passed before, why
is that needed ?
