[Lxc-users] Unable to SSH to the containers.

Tue Feb 9 11:03:45 UTC 2010

Hi Daniel,
Sorry for the delay while replying.
I am able to SSH from container to Host machine, but not able to do the
same from Host to container.
Please find the requested information below.

lxc-start is to launch /sbin/init

Please can you provide after launching both container:
 - the result of ifconfig on the host
 - the result of 'brctl show"
