This is the wrong way to approach this priblem since it moves a key configuration parameter outside the scope of the libvirt API. The second problem is that it is a single file per host, whereas libvirt can have multiple independant dnsmasq instances per host each with different config. If the problem is that we're getting too many --dhcp-host args causing us to hit command line length limits, then we should switch to using --dhcp-hostsfile and write out a per-dnsmasq config file in /var/lib/libvirt/network/$NETWORKNAME.dhcpmap Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
