vGPU - which graphics card supported?

AllooTikeeChaat · 6 Mar 2019, 18:58

AMD were making a lot of noise about the Pro V430 when it released and how it stacked up against the equivalent NV card. Not sure on where to get the Pro V430 .. those would be have been provided by AMD and eventually alway had to go back ...

The S7150x2 and other MxGPU's are available from the likes of Scan, I'm surpised that they don;t sell the Pro v430.

I found the Pro v430 being sold ar Insight and its spendy $9k - not sure what the performance would be like and is it worth 3x the price of the S7150x2 ? The S7150x2 was a good as the Nv M60 in our testing.

You should be able to get the S7150 and get 3 for the price of a single Pro v430 from most resellers:

@AllooTikeeChaat
Cheers, your insight is much appreciated.

We might look into a S7150 in the future!

We were also looking into gvt-g supported CPUs.
Has anyone tested those with xcp-ng?

Managed to get the AMD S7150x2 working with xcp-ng 7.6 week ago. No idea how it stacks up performancewise with anything else as it is my first adventure in VM shared video.

I can post details Monday when I am back I the office, but I just installed XCP-NG and loaded the Citrix driver from AMD's website and it worked. Much more sane install than my attempt at Hyper-v. The mxgpu settings page gives me the ability to set the you slices and everything. Performance in one test guest feels pretty decent.

Overall I'm very impressed by XCP-NG so far.

@Arvee thanks a LOT for the feedback. Ideally, if you can, please update the Wiki (write permissions for everyone) to explain the exact steps you did

Feel free to create a vGPU page and make a dedicated paragraph for AMD GPUs

@Arvee

Well done.. the S7150x2 should be a a fair bit faster than the K2/K1 grid cards. For CAD/Architectural workloads we found it as fast as Nvidia M60 and sometimes faster .. using the same GPU profile types.

Arvee · 10 Jun 2019, 16:33

@OLIVIERLAMBERT will do. I'll try and get that rolling today or tomorrow.

The only complaint the remote person had was the mouse was "jumpy" in Autocad which is likely due to an RDP latency issue. We'll do some more tuning on that and see where it ends up. If it eludes me much more I'll post a separate topic for that.

AllooTikeeChaat · 10 Jun 2019, 16:55

@Arvee

We were always deploying using Xendesktop/XenApp - performance once configured correctly - GPO's HDX policies was usually very good - apps workloads Autocad, Revit and Inventor Pro. No longer have access to all the tweaks.

Not sure how you'd tune and tweak RDP to improve the performance.

olivierlambert · 10 Jun 2019, 17:22

Yeah, XenDesktop (and in general Citrix HDX protocols) are great for those cases.

I don't know about UDS, if it uses something else than RDP.

I am running a WX7100 under XCP-ng 7.6. It only allows full GPU passthrough. So you can run multiple VMS on the server, but only one at a time can be assigned the GPU. I have tested it to work properly with Server 2016 std, Server 2019 std, and Win10 pro. Currently I have it crunching BOINC under win10pro and here are the stats.... BOINCstats for Norby

Hello,

We are using XCP-ng at our University, and are looking to purchase either Radeon Instinct MI50 or MI60 GPU:s (running on HPE ProLiant Gen10).

So am I correct to assume that vGPU works for these AMD cards? Just want to confirm, as the hardware costs quite a bit

olivierlambert · 4 Sept 2019, 08:50

All the input you can have in within this thread. We don't have this kind of hardware here so I can't tell you myself.

biztems · 2 Oct 2019, 08:06

@Arvee

Do you remember during your testing of the S7150 in MxGPU mode if it supported 4K resolutions for guests?

Thanks!

Arvee · 2 Oct 2019, 19:31

@biztems

I did not test 4K but it looks like it is at least supported by the drivers. Not sure how well the S7150 would do with that as it is fairly old, but it appears to be there.

Thank you very much for your help! It should be okay - we're not going to do CAD or anything on it, just large pictures and 4K videos (and those should be decoded entirely in hardware by the S7150, AFAIK).

Thanks again!

@biztems keep us posted please We'd like to know the result!

Yep, just bought one, will report soon

Thanks, with this info we'll be able to update the Wiki to provide more guidance for people who wonder about those great GPUs and XCP-ng support

Welp, we've already encountered our first issue - the MxGPU supplemental pack expects kernel-4.4. It also seems AMD isn't really intent on updating it anymore (last update was more than a year ago) and the V340 only supports VMware (boo!), which paints quite a dire outlook for our VDI dreams on XCP-ng

We're rolling back to XCP-ng 7.6 in the meanwhile - but would there be any way of running kernel-4.4 on XCP-ng 8.0+?

Cheers!

olivierlambert · 16 Oct 2019, 13:19

IIRC, it was doable to rebuild a pack ourselves to work with a more recent kernel At least, everything is on GitHub, so except if there is something very specific that won't apply on a more recent kernel, we could do it!
