vGPU - which graphics card supported?



  • Hello,

    Has anyone managed to get XCP-ng 8.1 working with AMD S7150 MxGPU?
    I got it working on 7.6 with the 1.05 AMD driver but 8.1 with the new 2.0 AMD driver doesn't give any virtual functions.
    Does someone have a working setup with XCP-ng 8.1 + AMD S7150(x2) ?

    Citrix and AMD apparently haven't provided any updated MxGPU packages for 8.0/8.1, so it relies on us and on the community to do it. There's been work on this but no working result for now: https://github.com/xcp-ng/xcp/issues/200



  • I tested with xcp-ng 8.1 with latest AMD Driver 2.0 (6/22/2020) and It works fine. But I don't know how can I see the temperature of AMD 7150 card

    Yes. For me It works fine

    That might be interesting info for @r1

    @savage79 What is the AMD advised way of knowing temperature of the card on Linux machines?



  • Ok. So I did some extensive testing with the FirePro S7150x2 card. While SR-IOV works OK in XCP-ng 8.1 with the 2.0 AMD host drivers, unfortunately there is no codec engine (VCE) support in the VMs. So while there is nice accelerated graphics in the VM itself, it is not possible to use any modern high performance remoting protocol that uses hardware encoding. My use case would've needed Parsec to work, but unfortunately Parsec requires VCE engine that is available only via passthrough and not SR-IOV. I have confirmation about this from AMD so VCE is not available for MxGPU on the S7150x2. It might work for the newer cards but the Instinc cards for example are not available retail, just through other channels. So for my use case, the only solution appears to be Intel GVT-g. Anyone had any success with GVT-g Quicksync support in VMs?

    I wonder why AMD isn't selling its more modern Pro cards on the market directly?



  • Same reason nVidia isn't selling them directly either. I guess it's business policy. For some reason they are holding on to GPU virtualization technology very tightly. I understand the nVidia GeForce Now concept and the fact that they don't want competitors for their cloud gaming service. Also, other big cloud providers are working on their own solutions. SR-IOV is available technology since many years now and it is open source. It is a simple and elegant solution for resource sharing. MxGPU works, so it can be done. Why not enable SR-IOV on lesser performance cards or Quadro cards? That would make competing with the big GRID cards impossible but give access to the technology for people who need it.



  • Is anyone using vGPU on the XCP-ng yet? If so i would like to know the setup.

    Iam running 1xE1230v5 on SuperMicro Server (X11SSL-F). Only got one PCI-E 3.0 x8 free for use. Would mind its not worth to get it a try on this machine.

    vGPU is very interesting at all and would be a huge part to take over other virtualization solutions.
