Has anyone successfully implemented "wake on LAN" functionality in a linux container?
In my setup each client has his own container for a vpn, but I only want the container to "boot up" when the client connects to it. One idea I had is to use internal DNS to resolve the container, and start it when a DNS request is received. However it would be far simpler if there was some sort of "wake on lan" functionality I could use.
The closest I could find is lxc checkpointing, which is not yet implemented.
