[Lxc-users] Fwd: Container inside an ESX VM

[Mauras Olivier]

So some more testing today. Here's what happens:
When i have one container up with my host network restart trick,
everything's fine, i can download gigas of data without problem.
Starting a second one, redo the network trick to have network in this one
either, everything looks ok.
About 5minutes later interface get shut down and kernel panic...

That's all for today :D
