Could not install Nvidia driver and CUDA 7.5 on Openstack VM (with Tesla K80/k40 passthrough)

I wanna to install Nvidia driver and CUDA 7.5 in the virtual machine with CentOS 7,but did not get lucky.

On the physical machine,the driver works well,and CUDA “devicequery” can get the Tesla GPU information.

Then I enabled “IOMMU” and “vfio” for the GPU passthrough,config Openstack with pci_passthrough and pci_alias,also created flavor,the provisioning of VM is good and I can see the GPU device in the VM,but the installation of Nvidia driver failed.

Here are current config, any advises? Thanks.

  1. On Nova host physical machine
    IOMMU is enabled

[root@kilo-k40 ~]# dmesg |grep -e IOMMU

  1. in the virtual machine

the GPU device is there.

the “nouveau” has been added to the modprobe blacklist
