Hi,
I recently did fresh Ubuntu install with LXC.
After starting container in non-daemon mode ($lxc-start -n trusty-raw) it
showed errors and foreground process hangs.
I am able to stop the container from another terminal.
Although the container starts in daemon mode ($lxc-start -n trusty-raw -l
debug -o start_daemon.log) but after ssh and executing sudo command gave
following error:
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the
'nosuid' option set or an NFS file system without root privileges?
My system config is:
Ubuntu 14.04.1 LTS 3.13.0-36-generic x86_64 GNU/Linux, with lxc version
1.0.5-0ubuntu0.1
I am also attaching both log file (container started with and without
daemon mode).
The user-space containers were working on my previous installation.
(Ubuntu 14.04 LTS with one/ two minor version back kernel and
1.0.5-0ubuntu0.1 lxc version).
Can someone guide me, if am I missing anything.
(i have configured my user-space containers with help from:
https://www.stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/)
Thanks
Nilesh
