August 18, 20196 yr Hi, I have 2 gaming-VM's om my computer. Both of them seems to work ok, but when gaming they both have lag and allso extreme delay when moving. Allso runs smooth a few secound now and then. Computer specs: i5-9600K ASUS TUF Z390-PLUS GAMING (WI-FI) 32GB ram 2x ASUS GTX1070-Turbo 8GB 240GB M.2-SSD 1TB SSD I finally got rid of the error code 43 when using: PCIe ACS override: Downstream VFIO allow unsafe interrupts: Yes Bios: OVMF Machine: Q35-3.1 I don't think there is any problem with the graphic card now. Even doh nvidia control panel shows; PCI Express x1. Both cards is placed in x16 lanes. Windows 10 power plan is set to high preformance and in BIOS i have tried pcie speed gen2, 3 and AUTO. All give same results. Even pcie x1 should work just fine. A little lower fps, but stable. I think there is a CPU problem. I have been google'ing and i found a lot about cpu cache and memory. But im noob, i dont understand what to test. My CPU does not have HT and i only have 1 CPU. All the other ppl i read about have HT and more than 1 cpu. I switched one of the VM's to use CPU Mode: Emulated (QEMU64), this works a lot better! It is now possible to play, but it's still not good enough to play FPS games. Not sure if this is useful, but i typed in some commands i found in other forum thread: numactl --hardware available: 1 nodes (0) node 0 cpus: 0 1 2 3 4 5 node 0 size: 32082 MB node 0 free: 321 MB node distances: node 0 0: 10 numastat qemu Per-node process memory usage (in MBs) PID Node 0 Total ----------------------- --------------- --------------- 4725 (qemu-system-x86) 12392.18 12392.18 14377 (qemu-system-x86) 16489.20 16489.20 ----------------------- --------------- --------------- Total 28881.38 28881.38 Thanks for any help! tower-diagnostics-20190818-0731.zip
August 23, 20196 yr Try the commands in XML mode listed by testdasi for x16 pci-e. But overall bump to 2 vCPUs minimum if you can afford to.
