+Subject: [PATCH] Read MAC address from libvirt and pass up to Vagrant
+
+Configuring networks based solely on slot numbers doesn't work very
+well, since there's no way to guarantee that the interface Vagrant
+finds is the same one that vagrant-libvirt created at that index.
+
+For example, Vagrant's Fedora configure_networks action does this:
+
+  machine.communicate.sudo("ls /sys/class/net | grep -v lo") do |_, result|
+    interface_names = result.split("\n")
+  end
+
+  interface_names = networks.map do |network|
+    "#{interface_names[network[:interface]]}"
+  end
+
+which means that if your image has 'docker' pre-installed, then
+interface_names[0] = "docker0" and hilarity ensues, with the first
+non-management network being assigned to the vagrant-libvirt
+management interface.
+
+Since interface names are very unreliable (they can be renamed by
+udev at will or when hardware changes) the only way to ensure that
+the interface vagrant-libvirt attaches to the domain maps to the
+correct one inside the VM is by MAC address.  Pull the MAC address
+out of the libvirt config once the interface has been attached and
+pass that up to Vagrant so we have a chance of doing the right thing.
