Then I have secondary addresses for each server and I have to decide
manually
I have a lxc host (zoo 129.69.1.68) with a container (vmtest8 129.69.8.6).
I want all host/container communication to be internal without network
traffic going via external router.
I know I can setup host routes like:
root@vms2:# route add -host 129.69.8.6 gw 129.69.1.68
root@vms2:# route -n

Other ideas for a suspend mode?
AFAIK, there's nothing to implement a network freeze. A by the way, what

The same behaviour as with vmware. There I have a real suspend mode.
If you were to freeze a network stack for
Is there a way to get the corresponding host PID for a container PID?
For example: inside the the container the process init has always PID 1.
But what PID has this process in the host process table?
ps aux | grep ... is not what I am looking for, I want more robust solution.

Thought about it some more and i think it might be an advanced esx

Then the first rename (eth1 -- dev3) should also fail.
But this works and the container starts und runs perfectly.
What fails is the renaming back

when I stop the container and try to restart it, eth1 is no more availble.
Looks lxc eats this interface. How can I free it (without rebooting the
host (zoo))?
