VScaler: vGPU Configuration

1. Yum install kernel kernel-devel -y 2. reboot 3. Download latest NVIDIA GRID software/drivers for RHEL KVM from here https://nvidia.flexnetoperations.com/control/nvda/download?agree=Accept&element=10189877 4. Yum install gcc glibc -y 5. Rpm -iv NVIDIA-vGPU-rhel-7.5-390.72.x86_64.rpm 6. Reboot 7. Check with: a. lsmod | grep vfio b. Nvidia-smi 8. cp /usr/lib/nvidia/systemd/nvidia-vgpu* /usr/lib/systemd/system/ 9. Systemctl start nvidia-vgpu-mgr.service  10. Systemctl enable nvidia-vgpu-mgr.service  11. systemctl start nvidia-vgpud.service 12. systemctl enable nvidia-vgpud.service 13. Check the /sys/class/mdev_bus/0000\:05\:00.0/mdev_supported_types/ directories and select one of the supported devices, eg nvidia-101 14. Create uuids and vgpu devices with them FOR EACH PHYSICAL GPU: a. uuidgen b. echo "af88fbf2-0110-4669-ab84-d747e9a9c19c" > /sys/class/mdev_bus/0000\:05\:00.0/mdev_supported_types/nvidia-101/create  15. Disable ECC on the GPUs on the host 16. Add the following to nova.conf of the gpu nodes: [devices] enabled_vgpu_types = nvidia-84 17. Add the following to nova.conf of the controller nodes: [scheduler] driver = filter_scheduler

[filter_scheduler] available_filters = nova.scheduler.filters.all_filters enabled_filters = AvailabilityZoneFilter, ComputeFilter, ComputeCapabilitiesFilter, ImagePropertiesFilter, ServerGroupAntiAffinityFilter, ServerGroupAffinityFilter 18. Do a kolla-ansible reconfigure to apply the above settings 19. Create a flavor with the following property: a. --property "resources:VGPU=1
