libvirt - recreation of virbr0 on update

libvirt creates network devices virbr0.  I remove the device with:

# virsh net-destroy default
# virsh net-undefine default
# systemctl restart libvirtd.service

Each time libvirt is updated, virbr0 comes back.  I have not found a way to keep it from coming back.

Any ideas would be much appreciated.

I've solved it by having the symlink:

/etc/libvirt/qemu/networks/autostart/default.xml -> /dev/null

This is a packaging problem, isn't it? Libvirt not only recreates the default network if it's missing, but also sets it to start automatically. The latter is the real issue, IMHO it shouldn't be doing this.

Good point, lightdot.  I'll file a bug report.
