Regarding the bigger point, I think it's worth considering whether we should aim to expose every requested dnsmasq option as official XML or not. We effectively have one network driver; there's an impl for vbox and esx but they seem very basic. It doesn't look like we are going to have another backend impl any time soon. Unless the requested option has some specific reason to be represented in libvirt XML, like if another part of libvirt may need/want to programmatically act on that data for some reason, maybe it's okay to say that dnsmasq passthrough is the solution. Some examples might be * dhcp-option: https://bugzilla.redhat.com/show_bug.cgi?id=666556 * auth-zone: https://bugzilla.redhat.com/show_bug.cgi?id=1690943 * This bug has a lot of mentioned options: https://bugzilla.redhat.com/show_bug.cgi?id=824573 - Cole -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
