I'm trying to take advantage of libvirt's support for passing through options to dnsmasq, but I'm having trouble getting it to take effect. I have a network already created and I'm trying to use net-update to add the options, but it's not clear to me what section I should specify. By the way, is there a good way to list the available sections? I've been resorting to reading the code. Working in a different direction, I tried using net-edit to make the changes but they seem to have been silently discarded:

    $ virsh -c qemu:///system net-edit crawford-libvirt-67v2h
    Network crawford-libvirt-67v2h XML configuration edited.

    $ virsh -c qemu:///system net-dumpxml crawford-libvirt-67v2h | grep --count <my changes>

    0

Can anyone tell me what I'm doing wrong or how this feature was intended to be used? Thank you.
