batman-adv: Unable to add interface in LXC

batman-adv: Unable to add interface in LXC

[Pau Koning]

I am running LXC (SID) under Debian SID and the current git version of
batman-adv (v3.7-rc7-1325-gaf5d4f7) +batctl (v2012.4.0-30-ga395164).
But it fails to add any of my interfaces and non-batman-adv interfaces
can be created without problems

Did you check your kernel log messages ? I'd expect batman-adv to print 
something there in case of an error.

No output at all

Sorry for the long delay. However batman-adv does not support lxc at the moment.
Therefore the error you are getting is likely to be related to this.
