Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

The setup is ubuntu 12.04 updated to the 3.8 kernel to be able to use juju locally, container created using bootstrap, but it does not start:

jmerelo@amy:~$ sudo lxc-start -n jmerelo-local-machine-1
lxc-start: failed to spawn 'jmerelo-local-machine-1'

The only problem in kern.log seems to be this

Nov 20 16:01:39 localhost kernel: [ 2102.918295] device veth7dHIov entered promiscuous mode
Nov 20 16:01:39 localhost kernel: [ 2102.919082] IPv6: ADDRCONF(NETDEV_UP): veth7dHIov: link is not ready

But I'm not sure it's related at all, except for the weird bridge name. Any idea of where I shoudl look? Or why it does not work?

I have restarted the machine and can confirm I am running in the new kernel.

Have you restarted the machine since you upgraded the kernel? Alternatively perhaps restart networking? –  thumper Nov 21 '13 at 3:07
Yep, restarted and checked that the new kernel was running. –  jjmerelo Nov 21 '13 at 8:59
