Exploring SR-IOV with AMD S7150 and Instinct MI25 for Virtualized GPU Workloads

Guide:

Introduction: This guide aims to explore the viability of SR-IOV (Single Root I/O Virtualization) using AMD S7150 and Instinct MI25 GPUs for virtualized GPU workloads. These GPUs, although aging, may offer a cost-effective solution for running multiple concurrent VMs. Follow the steps below to assess their functionality and potential limitations.

Requirements:

  • AMD S7150 or Instinct MI25 GPU
  • Motherboard with PCIe slots and SR-IOV support
  • Understanding of virtualization concepts
  • Patience and attention to detail

Step 1: Check SR-IOV Compatibility:

  1. Verify that your motherboard supports SR-IOV. Consult the motherboard manual or manufacturer's website.
  2. Ensure that the BIOS/UEFI firmware is up-to-date.

Step 2: AMD GPU Compatibility:

  1. Confirm that your AMD S7150 or Instinct MI25 GPU supports SR-IOV. Check the official AMD documentation for details.
  2. Verify that the GPU is in working condition by testing it in a single-user environment.

Step 3: Install Hypervisor with SR-IOV Support:

  1. Choose a hypervisor with SR-IOV support. Popular choices include VMware ESXi, KVM/QEMU, and Microsoft Hyper-V.
  2. Follow the installation guide for your selected hypervisor.

Step 4: Enable SR-IOV in BIOS/UEFI:

  1. Access the BIOS/UEFI settings of your motherboard during boot.
  2. Locate the SR-IOV option and enable it. Save changes and exit.

Step 5: Configure SR-IOV in Hypervisor:

  1. Access the hypervisor management interface.
  2. Navigate to the settings related to GPU passthrough and SR-IOV.
  3. Enable SR-IOV for the AMD GPU.

Step 6: Create Virtual Machines:

  1. Using your hypervisor, create multiple virtual machines.
  2. Assign the SR-IOV-enabled AMD GPU to each virtual machine.

Step 7: Install GPU Drivers in VMs:

  1. Install the necessary GPU drivers within each virtual machine.
  2. Verify that the AMD GPU is recognized and functioning correctly.

Step 8: Test GPU Workloads:

  1. Run GPU-intensive workloads in each virtual machine to assess performance.
  2. Monitor for any stability issues or limitations.

Step 9: Troubleshooting:

  1. If you encounter issues, consult the hypervisor's documentation and community forums for troubleshooting guidance.
  2. Check for firmware updates for both the motherboard and GPU.

Step 10: Community Support:

  1. Engage with the virtualization and GPU pass-through communities for support.
  2. Share your experiences and seek advice on forums or relevant platforms.

Conclusion: SR-IOV with AMD S7150 and Instinct MI25 GPUs can offer a cost-effective solution for running multiple concurrent VMs. However, success may depend on the compatibility of your motherboard, GPU, and hypervisor. By following these steps and seeking community support, you can explore the full potential of SR-IOV with these aging but potentially valuable GPUs. Good luck with your virtualized GPU workloads!

Is SR-IOV via an AMD S7150 or Instinct MI25 card functional these days?

Hey there, trying to get a handle on the viability of vGPUs with those 2 now very ancient SR-IOV capable AMD Polaris/Vega cards as they're probably the only 2 sub $200 cards floating around online that seem theoretically capable.

As you probably guessed, yes I'm trying to run multiple concurrent VMs, and unfortunately, my motherboard is PCIe slot-scarce so only 1 GPU (no support for bifurcation) is an option. I do have a 6800XT as a backup if I'm forced to go single-user, but ideally id like to try to make it work (without sourcing a V520/V620 for $$$)
