Hello, I'm trying to build a container that will be able to use the GPU capabilites of my nvidia graphic card. My distribution is an Ubuntu 12.04 and I downloaded the package "cuda_5.0.35_linux_64_ubuntu11.10-1.run". From the nvidia site. I've installed the nvidia driver, the nvidia devkit and also some samples. Everything run fine on the host. Then I installed a container and I added the following in my config file:
lxc.cgroup.devices.allow = c 195:* rwm # for nvidia I can start and log into my container. Then I created /dev/nvidia0, /dev/nvidia1 and /dev/nvidiactl in the container. I installed the cuda development kit and some samples but when I run a test I get: ~/NVIDIA_CUDA-5.0_Samples/0_Simple/clock$ ./clock CUDA Clock sample CUDA error at ../../common/inc/helper_cuda.h:930 code=35(cudaErrorInsufficientDriver) "cudaSetDevice(devID)" CUDA error at ../../common/inc/helper_cuda.h:931 code=35(cudaErrorInsufficientDriver) "cudaGetDeviceProperties(&deviceP rop, devID)" GPU Device 0: "" with compute capability 8592.1001 I've also tested to remove the nvidia driver from the host and install it into the container but insmod failed into the container. I get the following error: Kernel module compilation complete. Kernel module load error: insmod: error inserting './kernel/nvidia.ko': -1 Operation not permitted So in short: - when I installed the nvidia driver into the host, I cannot access GPU from the container - when I tried to install the nvidia driver into the container I cannot do the insmod. In both cases I let "lxc.cgroup.devices.allow = c 195:* rwm # for nvidia" into the config file of the container. What can I try next?
