[lxc-devel] [PATCH] return lxc generated name for veth pair

[Serge Hallyn]

Quoting Dwight Engen (dwight.engen at oracle.com):
> Doing a get_config_item for lxc.network.0.veth.pair only returns the
> pair name if explicitly given, but it can be useful to know the name
> even if it is the one that lxc autogenerated.
