Attaching a GPU to an Ubuntu Linux VM on Azure Stack HCI

  • Article

Applies to: Azure Stack HCI, version 22H2

This topic provides step-by-step instructions on how to install and configure an NVIDIA graphics processing unit (GPU) with Azure Stack HCI using Discrete Device Assignment (DDA) technology for an Ubuntu virtual machine (VM). This document assumes you have the Azure Stack HCI cluster deployed and VMs installed.

Install the GPU and then dismount it in PowerShell

  1. Install the NVIDIA GPU(s) physically into the appropriate server(s) following OEM instructions and BIOS recommendations.

  2. Power on each server.

  3. Sign in using an account with administrative privileges to the server(s) with the NVIDIA GPU installed.

  4. Open Device Manager and navigate to the other devices section. You should see a device listed as "3D Video Controller."

  5. Right-click on "3D Video Controller" to bring up the Properties page. Click Details. From the dropdown under Property, select "Location paths."

  6. Note the value with string PCIRoot as highlighted in the screen shot below. Right-click on Value and copy/save it.

  7. Open Windows PowerShell with elevated privileges and execute the Dismount-VMHostAssignableDevice cmdlet to dismount the GPU device for DDA to VM. Replace the LocationPath value with the value for your device obtained in step 6.

    Dismount-VMHostAssignableDevice -LocationPath "PCIROOT(16)#PCI(0000)#PCI(0000)" -force

  8. Confirm the device is listed under system devices in Device Manager as Dismounted.

Create and configure an Ubuntu virtual machine

  1. Download Ubuntu desktop release 18.04.02 ISO.

  2. Open Hyper-V Manager on the node of the system with the GPU installed.

    Note

    DDA doesn't support failover. This is a virtual machine limitation with DDA. Therefore, we recommend using Hyper-V Manager to deploy the VM on the node instead of Failover Cluster Manager. Use of Failover Cluster Manager with DDA will fail with an error message indicating that the VM has a device that doesn't support high availability.

  3. Using the Ubuntu ISO downloaded in step 1, create a new virtual machine using the New Virtual Machine Wizard in Hyper-V Manager to create a Ubuntu Gen 1 VM with 2GB of memory and a network card attached to it.

  4. In PowerShell, assign the Dismounted GPU device to the VM using the cmdlets below, replacing the LocationPath value with the value for your device.

    # Confirm that there are no DDA devices assigned to the VM
Get-VMAssignableDevice -VMName Ubuntu

# Assign the GPU to the VM
Add-VMAssignableDevice -LocationPath "PCIROOT(16)#PCI(0000)#PCI(0000)" -VMName Ubuntu

# Confirm that the GPU is assigned to the VM
Get-VMAssignableDevice -VMName Ubuntu

    Successful assignment of the GPU to the VM will show the output below:

    Assign GPU Screenshot.

    Configure additional values following GPU documentation here:

     # Enable Write-Combining on the CPU
 Set-VM -GuestControlledCacheTypes $true -VMName VMName

 # Configure the 32 bit MMIO space
 Set-VM -LowMemoryMappedIoSpace 3Gb -VMName VMName

 # Configure greater than 32 bit MMIO space
 Set-VM -HighMemoryMappedIoSpace 33280Mb -VMName VMName

    Note

    The Value 33280Mb should suffice for most GPUs, but should be replaced with a value greater than your GPU memory.

  5. Using Hyper-V Manager, connect to the VM and start the Ubuntu OS install. Choose the defaults to install the Ubuntu OS on the VM.

  6. After the installation is complete, use Hyper-V Manager to shut down the VM and configure the Automatic Stop Action for the VM to shut down the guest operating system as in the screenshot below:

    Guest OS Shutdown Screenshot.

  7. Log in to Ubuntu and open the terminal to install SSH:

     $ sudo apt install openssh-server

  8. Find The TCP/IP address for the Ubuntu installation using the ifconfig command and copy the IP address for the eth0 interface.

  9. Use an SSH client such as OpenSSH (ssh.exe installed with Windows 10 by default) or Putty to connect to the Ubuntu VM for further configuration.

  10. Upon login through the SSH client, issue the command lspci and validate that the NVIDIA GPU is listed as "3D controller."

    Important

    If The NVIDIA GPU is not seen as "3D controller," please do not proceed further. Please ensure that the steps above are followed before proceeding.

  11. Within the VM, search for and open Software & Updates. Navigate to Additional Drivers, then choose the latest NVIDIA GPU drivers listed. Complete the driver install by clicking the Apply Changes button.

    Driver Install Screenshot.

  12. Restart the Ubuntu VM after the driver installation completes. Once the VM starts, connect through the SSH client and issue the command nvidia-smi to verify that the NVIDIA GPU driver installation completed successfully. The output should be similar to the screenshot below:

    Screenshot that shows the output from the nvidia-smi command.

  13. Using the SSH client, set up the repository and install the Docker CE Engine:

    $ sudo apt-get update
$ sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common

    Add Docker's official GPG key:

    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

    Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 by searching for the last eight characters of the fingerprint:

    $ sudo apt-key fingerprint 0EBFCD88

    Your output should look similar to this:

    pub   rsa4096 2017-02-22 [SCEA]
9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>
sub   rsa4096 2017-02-22 [S]

    Set up the stable repository for Ubuntu AMD64 architecture:

    $ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

    Update packages and install Docker CE:

    $ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io

    Verify the Docker CE install:

    $ sudo docker run hello-world

Configure Azure IoT Edge

To prepare for this configuration, please review the FAQ contained in the NVIDIA-Deepstream-Azure-IoT-Edge-on-a-NVIDIA-Jetson-Nano GitHub repo, which explains the need to install Docker instead of Moby. After reviewing, proceed to the steps below.

Install NVIDIA Docker

  1. From the SSH client, add package repositories:

    curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)

curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update

  2. Install nvidia-docker2 and reload the Docker daemon configuration:

    sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd

  3. Reboot the VM:

    sudo /sbin/shutdown -r now

  4. Upon reboot, verify successful installation of NVIDIA Docker:

    sudo docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi

    Successful installation will look like the output in the screenshot below:

  5. Following the instructions here, proceed to install Azure IoT Edge, skipping the runtime install:

    curl https://packages.microsoft.com/config/ubuntu/18.04/multiarch/prod.list > ./microsoft-prod.list

sudo cp ./microsoft-prod.list /etc/apt/sources.list.d/

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo cp ./microsoft.gpg /etc/apt/trusted.gpg.d/
sudo apt-get update

sudo apt-get install iotedge

    Note

    After installing Azure IoT Edge, verify that the config.yaml is present on the Ubuntu VM at /etc/iotedge/config.yaml

  6. Create an IoT Edge device identity in the Azure portal following guidance here. Next, copy the device connection string for the newly created IoT Edge.

  7. Using the SSH client, update the device connection string in config.yaml on the Ubuntu VM:

    sudo nano /etc/iotedge/config.yaml

    Find the provisioning configurations of the file and uncomment the "Manual provisioning configuration" section. Update the value of device_connection_string with the connection string from your IoT Edge device. Make sure any other provisioning sections are commented out. Make sure that the provisioning: line has no preceding whitespace and that nested items are indented by two spaces:

    Manual Provisioning Configuration Screenshot.

    To paste clipboard contents into Nano, shift+right click or press shift+insert. Save and close the file (Ctrl + X, Y, Enter).

  8. Using the SSH client, restart the IoT Edge daemon:

    sudo systemctl restart iotedge

    Verify the installation and check the status of the IoT Edge daemon:

    systemctl status iotedge

journalctl -u iotedge --no-pager --no-full

  9. Using the SSH client, create the following directory structure on the Ubuntu VM:

    cd /var
sudo mkdir deepstream
mkdir ./deepstream/custom_configs
cd /var/deepstream
sudo mkdir custom_streams
sudo chmod -R 777 /var/deepstream
cd ./custom_streams

  10. Ensure your working directory is /var/deepstream/custom_streams and download the demo videos file by executing the following command in the SSH client:

    wget -O cars-streams.tar.gz --no-check-certificate https://onedrive.live.com/download?cid=0C0A4A69A0CDCB4C&resid=0C0A4A69A0CDCB4C%21588371&authkey=AAavgrxG95v9gu0

    Un-compress the video files:

    tar -xzvf cars-streams.tar.gz

    The contents of the directory /var/deepstream/custom_streams should be similar to the screenshot below:

    Custom Streams Screenshot.

  11. Create a new file called test5_config_file_src_infer_azure_iotedge_edited.txt in the /var/deepstream/custom_configs directory. Using a text editor, open the file and paste in the following code, then save and close the file.
