libvirtd starts by default a virtual closed network (which is NATed) for VMs. This is usually assigned an IP range in the 192.168.200.0/24 range, IIRC. And it is only available for VMs running on the box, started and configured by libvirt. And libvirtd uses dnsmasq for these services. To stop it, run these commands as root: # virsh virsh # net-list --all Name State Autostart Persistent ---------------------------------------------------------- default inactive no yes virsh # net-destroy default Network default destroyed virsh # 'destroy' sounds harsh and brutal, but in libvirt lingo, it means "stop running". To make this permanent, run this command in virsh virsh # net-autostart default --disable Network default unmarked as autostarted virsh # That's it. -- kind regards, David Sommerseth
