There's already a 'systemctl try-restart libvirtd.service' call just a
few lines below. 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).
I think the issue may be that the default network is in a different
sub-package than libvirtd, so libvirtd is already started/restart by the
time the file is installed. Or something like that. I do recall that
this is a real problem though.
I also meant to respond to this patch and again got distracted - when I
tried to manually do that this patch supposedly does, I got an error:
I copied a new XML file into /etc/libvirt/qemu/networks and a link for
it into /etc/libvirt/qemu/networks/autostart, then called systemctl
reload libvirtd.service, I ended up with a bridge device created with
the correct IP address, but libvirt showed the new network as inactive
and this error log:
networkCheckRouteCollision:121 : internal error: Network is already in
use by interface virbr3
(virbr3 is the bridge created for this network; it didn't exist prior to
telling libvirtd to reload, and there is no other route in conflict with
it.)
I didn't have time to investigate, but am wondering if the patch is
really doing what is intended.
