[lxc-devel] Hot-add network devices in LXC

[Carlos N. A. Corrêa]

Hi, people.

I'm trying to implement a mechanism to permit the addition of a new network
device to a container "on-the-fly".

That would be useful to me in some complex virtual networking scenarios,
where a container need to connect to a newborn bridge and I can't stand to
lxc-stop/modify config manually/lxc-start.

I'm thinking about:

1. Hacking commands.(h|c) to create a new callback for hot netdev addition
2. Implement the callback through a call to instanciate_(veth|macvlan|etc)
3. Updating lxc_handler->conf->network by adding a new netdev to the list

Could this be accomplished some other way? Do you think that it could be
useful to others?
