[lxc-users] DRI in LXD

[Pete Osborne]

I was able to get OpenGL functioning withing my LXD container by running
these commands from outside my container:

lxc config device add qt5-development /dev/nvidia0 unix-char
path=/dev/nvidia0
lxc config device add qt5-development /dev/nvidiactl unix-char
path=/dev/nvidiactl
lxc config device add qt5-development /dev/nvidia-uvm unix-char
path=/dev/nvidia-uvm
lxc config device add qt5-development /dev/video0 unix-char
path=/dev/video0
lxc config device add qt5-development /dev/tty0 unix-char path=/dev/tty0

lxc config device add qt5-development /dev/tty7 unix-char path=/dev/tty7
lxc config device add qt5-development /dev/tty8 unix-char path=/dev/tty8
lxc config device add qt5-development /dev/fb0 unix-char path=/dev/fb0
lxc config device add qt5-development /dev/dri unix-char path=/dev/dri
lxc config device add qt5-development /dev/dri/card0 unix-char
path=/dev/dri/card0

(some of these may be overkill)

I also needed to install the same NVIDIA drivers that are installed in teh
host, using the NVIDIA installer I needed to pass --no-kernel-module to the
installer, in my case this resulted in:

./NVIDIA-Linux-x86_64-340.96.run --no-kernel-module

I was able to test the implementation by running glxinfo from within my
container.

I can now compile and test Qt5 applications within my container with full
hardware acceleration,

Thanks again,
Pete
