I debugged this problem yesterday. Some nice people (Yes Daniel YOU!) have
added a stateful configuration together with libvirt. To get your xen
config working again do the following:

- go to /etc/libvirt/qemu/networks
- rm default.xml; rm autostart/default.xml
- cd /var/lib/xend/state/
- edit: network.xml, and remove the complete section of virbr0

(The last thing must be possible by some obscure xenstore-rm command, I
don't know it...)

Now if you got this far, reboot your pc, your virbr0 should be gone, and
everything works again. File your complaints to libvirt for automatic
screwups.
