They were added in 4789fb2e. I think we can use them - also, I'm not sure why it doesn't work since we are restarting daemon even now (without this patch).

Or something like that. I do recall that > this is a real problem though. Heh. And if I had taken the time to go read the BZ that Cole referenced in his commit log message, I would have seen that I came to that same conclusion all the way back in 2012 :-/ It's amazing just how much I forget... So I think this patch will be okay if we can just verify that it doesn't experience the same problem that I experienced when performing the reload manually.

checking if libvirtd is running, and sending the file to "virsh net-define" instead of copying it when that's the case?)
