Hi Daniel,

This is a libvirt question. I have CCed the libvirt mailing list so you
can continue discussion there.
On Red Hat-based distros try reinstalling the
libvirt-daemon-config-network package. On Debian-based distros try
reinstalling the libvirt-daemon-system package. This should restore the
/etc/libvirt/qemu/networks/default.xml file that you are missing.
No need to re-install those RPMs - Libvirt leaves a copy of the stock
XML
file at /usr/share/libvirt/networks/default.xml. So just run
virsh define /usr/share/libvirt/networks/default.xml
virsh start default
Regards,
Daniel
