Kill the dnsmasq manually and execute a new dnsmasq cmdline (with right dncp option), does this works?

You only need a interface in xml to configure the dhcp-option?

This is being worked on under bug 637055. See, for example, the following email on libvirt-list: https://www.redhat.com/archives/libvir-list/2013-March/msg00166.html
