[lxc-users] LTS 14.04 lxc-start fails with unprivileged container

[Heinz]

Hi,


on my little home server (Ubuntu LTS 14.04) I try to setup an unprivileged lxc container.
The creation of lxc containers is ok, but the start fails.
Opened an issue on github, got no reply so far so I try this list.
https://github.com/lxc/lxc/issues/339


According to the trace file (test6.log)  the cause seems to be this line:

 lxc-start 1412576991.028 ERROR lxc_start - Permission denied - failed to exec /sbin/init


So I checked permissions:

lxc01 at srv01:~$ ls -lisa /lxc01/.local/share/lxc/test6/rootfs/sbin/init15829 260 -rwxr-xr-x 1 427680 427680 265848 Jul 18 11:46 /lxc01/.local/share/lxc/test6/rootfs/sbin/initlxc01 at srv01:~$
From my point of view thats ok (the uid and gid fit to the ones in /etc/subuid and /etc/subguid and in the container config cat .local/share/lxc/test6/config)

LTS 14.04 comes with lxc version 1.05 
I installed the lxc 1.06 tar ball too (parrallel) but got the same error again.
