Hi All, Trying to spass through some Nvidia K80 GPUs to soem instance and have gotten to the place where Nova seems to be doing the right thing gpu instances scheduled on the 1 gpu hypervisor I have and for inside the VM I see:
root@gpu-x1:~# lspci | grep -i k80 00:06.0 3D controller: NVIDIA Corporation GK210GL [Tesla K80] (rev a1) And I can install nvdia-361 driver and get # ls /dev/nvidia* /dev/nvidia0 /dev/nvidiactl /dev/nvidia-uvm /dev/nvidia-uvm-tools Once I load up cuda-7.5 and build the exmaples none fo the run claiming there's no cuda device. # ./matrixMul [Matrix Multiply Using CUDA] - Starting... cudaGetDevice returned error no CUDA-capable device is detected (code 38), line(396) cudaGetDeviceProperties returned error no CUDA-capable device is detected (code 38), line(409) MatrixA(160,160), MatrixB(320,160) cudaMalloc d_A returned error no CUDA-capable device is detected (code 38), line(164) I'm not familiar with cuda really but I did get some example code running on the physical system for burn in over the weekend (sicne reinstaleld so no nvidia driver on hypervisor). Following various online examples for setting up pass through I set the kernel boot line on the hypervisor to: # cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.13.0-87-generic root=UUID=d9bc9159-fedf-475b-b379-f65490c71860 ro console=tty0 console=ttyS1,115200 intel_iommu=on iommu=pt rd.modules-load=vfio-pci nosplash nomodeset intel_iommu=on iommu=pt rd.modules-load=vfio-pci nomdmonddf nomdmonisw Puzzled that I apparently have the device but it is apparently nonfunctional, where do I even look from here? -Jon _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
