[Bug 1296681] [NEW] failed to change apparmor profile to lxc-container-default

[Hadmut Danisch]

Public bug reported:

Hi,

I've recently upgraded my machine to 14.04 beta and tried lxc. Worked
just fine (about 10 days ago).

After some daily updates of the machine I wanted to use lxc again, but
now I am running into this problem (the files in the cgroup_rmdir lines
haven sequence numbers like -1, -2, -3, -4,...)

# lxc-start -n meinerster
lxc-start: Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start: Device or resource busy - failed to set memory.use_hierarchy to 1; continuing
lxc-start: No such file or directory - failed to change apparmor profile to lxc-container-default
lxc-start: invalid sequence number 1. expected 4
lxc-start: failed to spawn 'meinerster'
