Thank you. > > -Alex The last time I tried using net-update, if I recall it didn't support full editing. I had to net-edit the network in question and restart it (to do exactly what you're tryint to do, I should note!). I don't think net-update lets you edit the root element's namespace (which is what you need to do for e.g. <dnsmasq:options> to not be eaten). For reference, the modified root element looks like this: <network xmlns:dnsmasq="http://libvirt.org/schemas/network/dnsmasq/1.0";> <!-- Normal network definition here... --> <dnsmasq:options> <dnsmasq:option value="log-dhcp"/> </dnsmasq:options> </network> -- brent saner https://square-r00t.net/ GPG info: https://square-r00t.net/gpg-info
