Package libvirt: can't disable default network
With usb boot:
After installation, I disabled and deleted the default network with
virsh net-undefine,
then saved it with lbu ci. After reboot it is still there.
Problem: livirtd init activate it after lbu loading.
Fix: disable or toggle the network creation in the init script from
libvirtd
