Yes, I saw your other e-mail too, but I'm afraid I can't help much as I
always have:
 - used xl only, when building Xen from sources, 
 - used Fedora Xen packages only, when using libvirt stuff

:-(

Ok.

On my Fedora 18, I get this:

$ yum search libvirt-daemon-driver-network
...
...
====================================================================================
libvirt-daemon-driver-network.x86_64 : Network driver plugin for the libvirtd 
daemon

$ rpm -qa | grep libvirt-daemon-driver-network
libvirt-daemon-driver-network-1.0.6-3.fc18.x86_64

Anyway, I do not think this could be the cause of your issue.

I see... Just shooting in the dark here, and forgive me if it's a stupid
question, but is libvirtd running?

Indeed. You can double check that with something like:

$ ps aux | grep xend

or:

# service xend status

Although, I'm not sure the latter will work, considering you're not
using any Fedora RPM/SRPM...

As I said, I'm really short in ideas/experience, sorry. Something I
would probably try is:
 - uninstalling your built version of Xen
 - installing Fedora 17's Xen packages
 - try libvirt with them

That would at least tell us more about where --if not what-- the issue
could be.

Dario
