Hi again, I was running the following kernel version: Linux picasso 3.2.0-18-generic #29-Ubuntu SMP Fri Mar 9 21:36:08 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Just did a full update, and got the following error: matiasb@picasso:~$ sudo lxc-start -n u1-server lxc-start: Permission denied - failed to umount 'dev/pts' lxc-start: failed to setup the new pts instance lxc-start: failed to setup the container lxc-start: invalid sequence number 1. expected 2 lxc-start: failed to spawn 'u1-server' matiasb@picasso:~$ uname -a Linux picasso 3.2.0-19-generic #30-Ubuntu SMP Fri Mar 16 16:27:15 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Still working when disabling apparmor. ** Tags added: apport-collected staging ** Description changed: A previously working container is not starting with last lxc updates: matiasb@picasso:~$ sudo lxc-start -n u1-server lxc-start: Permission denied - failed to mount 'proc' on '/usr/lib/lxc/root//proc' lxc-start: failed to setup the mounts for 'u1-server' lxc-start: failed to setup the container lxc-start: invalid sequence number 1. expected 2 lxc-start: failed to spawn 'u1-server' This seems similar to bug #947617. In fact, the workaround mentioned there (disabling apparmor) makes it possible to start the container again.
