[lxc-users] slow game graphics in lxc container

[manik sheeri]

I have a privileged `lxc` container running on Ubuntu 16.0.4 LTS.

I have noticed that the graphics of our game are very sluggish in container
compared to when running on host directly.

Could anyone point a reference as to what could be the cause ?

So I ran `glxgears` application inside the container. Though the
application ran fine but I saw the following info + errors on console:

    libGL error: failed to open drm device: Permission denied
    libGL error: failed to load driver: nouveau
    4057 frames in 5.0 seconds = 811.356 FPS
    4238 frames in 5.0 seconds = 847.557 FPS
    4251 frames in 5.0 seconds = 850.081 FPS
    4254 frames in 5.0 seconds = 850.743 FPS
    4253 frames in 5.0 seconds = 850.431 FPS
    4255 frames in 5.0 seconds = 850.949 FPS
    4253 frames in 5.0 seconds = 850.450 FPS
    4254 frames in 5.0 seconds = 850.733 FPS
    4250 frames in 5.0 seconds = 849.960 FPS
    4247 frames in 5.0 seconds = 849.254 FPS
