My base distro on this machine is Ubuntu 9.10 Server.  And I did pretty 
much the same thing for it as you did for F12.  I built debs for Xen 
3.4.1 and installed them, custom built the JF pv_ops dom0 kernel and 
installed it.  Libvirt was already installed at version 0.7.0 so I 
didn't touch it.  libvirt had worked fine for a few test KVM guests.  
But now I want the whole machine dedicated to Xen guests but I'd still 
like to use libvirt to manage the guests.  So how do I get 'virsh' to 
default to the xen:/// hypervisor and also how do I get it to connect to 
it?  There's nothing running on port 8000.  So this is a mystery.
