CUDA in LXC via LXD
# Suppose we already have LXD, and already add the default image repo as images:
# 1. Start a new Trusty LXC container
host:~$ lxc launch images:ubuntu/trusty/amd64 cuda-trusty
# 2. Download and install CUDA on *both* host & LXC container, from https://developer.nvidia.com/cuda-downloads
# Note that host and container have to have *exactly* the same driver version
# 3. Add necessary Nvidia devices to LXC container
host:~$ lxc config device add cuda-trusty nvidia0 unix-char path=/dev/nvidia0
host:~$ lxc config device add cuda-trusty nvidiactl unix-char path=/dev/nvidiactl
host:~$ lxc config device add cuda-trusty nvidia-uvm unix-char path=/dev/nvidia-uvm
# Now your container should have CUDA capability.
