Do I need to start container with X (level 5?). I tried these steps :
1. Start container in level 3.
2.  lxc-console into container
3. Run Xvfb (that returned error as)
#Xvfb :0 -screen 0 1024x768x16 -ac &
SELinux: Invalid object class mapping, disabling SELinux support.
(EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so failed
(/usr/lib/dri/swrast_dri.so: cannot open shared object file: No such
file or directory)
(EE) GLX: could not load software renderer
4. Run mwm
# mwm
Error: Can't open display: 0.0
I have set display to 0.0

If I start Xvfb with no options I still get the above errors.

Any idea on what I am missing?

Thanks,
