June 25, 20206 yr Hi, I need some assistance getting my Win10 VM up and running. Current/main problem: After changing GPU from VNC to my ASUS RogStrix (AMD VEGA 56) the VM seems not to be able to run or receiving a valid IP address. IMHO it must have something to do with the change of the GPU, because before changing (only running with VNC) it works flawless. I was able to connect via VNC Client, WebClient and RDP-Manager - no problems. But as soon as change the GPU (and the sound card as well) to my VEGA 56 the VM doesn't shown up in my LAN. I looked in the VM-LOG, but I can't see anything that could lead me to a solution or even know, what's exactly going on Below you'll find both logs. For better transparency, I'll put some key information what I've done so far / my settings. Set up a Win 10 VM on an unassigned drive (nvme0n1) with the following VM manager settings: network bridge = br0 and PCIe ACS override = “Both” with the following explicit settings for my VM: CPU= host passthrough machine = i440FX-4.2 BIOS = OVMF Hyper-V = No USB Controller = 3.0 (qemu XHCI) Primary vDisk Location = manual = /dev/nvme0n1 Primary vDisk Bus = virtIO GPU = VNC SoundCard = none unRAID confirms via "INFO-PopUp" that HVM and IOMMU are enabled (vt-d = active @ BIOS) Installed the virt-IO driver, updated Win10 with latest patches to get network interface and better display resolution Boot up the VM with GPU = VNC to check, if everything runs fine --> correct IP via DHCP. As mentioned above, connection via VNC and RDP works fine! And now it could be a little bit confusing due to my several tests with different configs - but nothing works. Addition: I already run these commands (listed in another thread HERE) to get rid of the mmap-error - that worked! But sadly it seems, that there is another problem.... echo 0 > /sys/class/vtconsole/vtcon0/bind echo 0 > /sys/class/vtconsole/vtcon1/bind echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind First try: I just tried to change GPU and SoundCard to my Vega 56 Result: VM gets no correct IP (gets a 169.xxx.xxx.xxx) - no chance to connect. Try failed! Second try: Changed the GPU/SoundCard and edited the syslinux-config (see below) Result: VM gets no correct IP (gets a 169.xxx.xxx.xxx) - no chance to connect. Try failed! Third try: Changed the GPU/SoundCard and edited the syslinux-config and vm-settings via XML (see below) Result: VM gets no correct IP (gets a 169.xxx.xxx.xxx) - no chance to connect. Try failed! Fourth try: Changed the GPU/SoundCard and edited the syslinux-config and leave the vm-settings untouched (no editing as mentioned below) Result: VM gets no correct IP (gets a 169.xxx.xxx.xxx) - no chance to connect. Try failed! Fifth, sixth, seventh try: Same as above but now with the tree different vbios found here --> Link to TechPowerUPs VEGA56 ASUS vBIOS Result: VM gets no correct IP (gets a 169.xxx.xxx.xxx) - no chance to connect. Try failed! Eight try: Rollback only GPU to VNC without changing syslinux --> VM gets correct IP - connected via VNC and RDP - no problems. Detailed Information for above mentioned edits Edited Syslinux configuration with the following parameter. vfio-pci.ids=1002:687f,1002:aaf8 Those IDs are: [1002:687f] 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

[AMD/ATI] Vega 10 HDMI Audio [Radeon Vega 56/64] (rev ff) Edited XML-Settings for VM Add a flag on the first virtual line below the BIOS that says multifunction='on' Changed the virtual devices to be on the same bus, and set the functions to the same as their host. <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x03' slot='0x00'

I tried a lot of different settings - nothing works and I still wonder, that e.g. in SpaceInvaders Video he just changed GPU and Soundcard and everything works fine. He doesn't changed any syslinux configuration nor XML-parameters within the VM-setup -- and it works flawlessly out of the box... 😭 Edited June 26, 20206 yr by Maddeen
June 26, 20206 yr Author Got it - found out, some settings seems to be self-evident - but not for me 1) Must change primary graphics to iGPU in BIOS 2) Leave iGPU Multi-Monitor disabled in BIOS 3) the HDMI Dummy seems to be placed in the iGPU Port - NOT in the GPU Port. After changing this three settings, everything works fine. Passthrough my Vega works. 🙌 Now back to the fine adjustments and then I'll give remote gaming a chance 🤩🤙 Edited June 26, 20206 yr by Maddeen
