Hey i have a problem with my Windows 10 VM
system overview
unraid OS Version 6.8.3 2020-03-05
CPU Intel Xeon E-1246v3
MB ASRock Z97 Extreme v6
GPU Gainward Nvidia 980Ti GS
a situation summary:
i shutdown my server for a few hardware upgrades, two NVMe SSDs for the cache and a 10GbE Card.
I also used that to do a BIOS Upgrade.
After that i started unraid and my array and followed this guide to change my cache drives
this worked fine for me. then as i wanted to start my Windows 10 VM i noticed that the GPU i have installed didn't showed up in the VM settings
I searched and found out that i need to enable IOMMU pass-through or Intel VT-d (for me) in my BIOS
since the BIOS settings got reset after the upgrade i checked everything again and booted my system up again.
my error:
Now the GPU showed up in my VM again and everything looked good so far.
but when i start the VM the following error occurs
internal error: qemu unexpectedly closed the monitor: 2020-06-16T17:56:01.149672Z qemu-system-x86_64: -device vfio-pci,host=0000:01:00.0,id=hostdev0,x-vga=on,bus=pci.0,addr=0x5: vfio 0000:01:00.0: group 1 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.
so i checked the IMMOU groups and i have no idea why it would group itself like that
VM settings
so i did some research and found this
but i didnt really get the solution so i wanted to ask what should i do.
enable PCIe ACS (also which one)
Or do that vfio-bind (and how)
