frodr Posted October 10, 2019 Share Posted October 10, 2019 Hi. Running benchmark tests on Windows 10 kvm show poor performance. I have allocate all 12 cores on the second cpu, Xeon Silver 4116, but benchmark tests show performance about as 4 core i5/I7. The vdisk is on the cache drive, which is a Raid 10 setup. Is this the performance we can expect. Or is some obvious setup changes I can do? Cheers, Frode Quote Link to comment
1812 Posted October 10, 2019 Share Posted October 10, 2019 you could follow the a setup guide for windows to start (and stop using qemu cpu and use host passthrough for starters) then you could adjust cpu pinning and finally, you could google "Unraid vm windows tuning" Quote Link to comment

I have followed part1 and part2 of SIO`s videos when setting up the kvm, it is running host passthrough. Can it be something wrong on this topic? GPU and Nvme ssd are passthrough. Googled I have. I will have another look at pinning. Quote Link to comment
1812 Posted October 11, 2019 Share Posted October 11, 2019 you'd need to post your full diagnostics file to start. it may also be a numa node issue. Quote Link to comment

What is the numa node issue? I ran into some other problem while trying to get a Trustmaster steering wheel to work? When starting the kvm, an error message "Did not find USB.....". And when making changes in the xml another error message: "unknown PCIe vendor.....". I have restarted the server, restored appdata, but the error is still there. The error seems to be related to the PCIe USB card. I see the PCIe card in System Devices, see picture.

glennv Posted October 12, 2019 Share Posted October 12, 2019 funny coincidence and could be totaly unrelated to your issue.Was struggeling to get a trustmaster to work in w10vm as well via a passed asmedia usb3+usbc controller.Same wheel worked fine on native w10machine with same drivers/software etc so was not a driver issue.Gave up after a week trying. Then for another reason i started suspecting the asmedia controller (was not always recognised on boot and often had to reseat the card and or reboot a few times for it to be recognised on my supermicro board. Also i could intermittently not get usb3 to work on osx vm)Bought from ebay a Sonnet allegro usb card (mainly for its native stellar osx support) and bam. Steering wheel works without issue without changing a thing in w10. And osx support is great as expectedSo if you have access to other usb cards, give it a try. Quote Link to comment

I changed th PCIe USB card, but still the same error messages. I moved the flash drive to the new Asmedia PCIe USB card, now I have 6 free mother board usb drives. After removing hosthevs in the xml that the error message was referring, the kvm started up. Now it is back to get the steering wheel running and look for performance improvements. The Aida64 app says processors running at 100 Mhz, that's strange. CPUmark running at 10000 with 8 cores and about 8000 with 4 cores. Quote Link to comment
bastl Posted October 12, 2019 Share Posted October 12, 2019 2 hours ago, frodr said: This usually happens if you have set a USB device in the VM setup page and it isn't connected at the time you startup a VM. Could be a mouse, keyboard or your steering wheel. At this point you can't see the earlier attached device in the normal VM settings tab, you have to remove the part at the bottom of the xml referring to that device. example for a passed through mouse: <source> <vendor id='0x0a12'/> <product id='0x0001'/> <address bus='3' device='3'/> </source> 36 minutes ago, frodr said: The Aida64 app says processors running at 100 Mhz, that's strange I never had Aida reporting the cpu clocks correctly in a KVM VM.

frodr Posted October 12, 2019 Author Share Posted October 12, 2019 Up and running with the wheel. Great! 8 out of 12 cores of a Silver 4116 gives passmark 10000. Passmark on Silver 4116 is 15509, 8/12 is 10000. So the kvm performs good. The Samsung 970 Pro, where the games are store, are on heat..... 67C. Quote Link to comment
bastl Posted October 12, 2019 Share Posted October 12, 2019 @frodr On heavy load temps in the 60's are normal. If you always see temperatures above 70 or 80 even in idle, than you have an issue. Is the NVME sitting behind an GPU? Quote Link to comment
