| dnsmasq from package 'dnsmasq-base' starts with a (from libvirt) generated configuration: /var/lib/libvirt/dnsmasq/default.conf. | |
| this configuration file is not directly editable because it gets overwritten from libvirt. | |
| there is no possibility to set 'no-dhcp-interface=eth0' per 'libvirt'. | |
| # ########################################################### | |
| # deactivate dhcp in dnsmasq per libvirt | |
| # dnsmasq listen on port 53 (dns) and 67 (dhcp) | |
