Anyone got this working with RTX? I have:
MSI MEG X570 ACE
Ryzen 3800X
MSI Gaming X Trio RTX 2080 SUPER
Looking to passthrough the RTX 2080 Super to VM as a single GPU, have tried it all, modded vbios, Q35 chipset, stubbed the usb controllers and passthrough.
If in the second pci slot there's no problem, with a GTX 970 in the primary. But i want to run the super at full x16 speed.
With the attached config and steps taken i get a screen output at 800x600 and i am unable to install the drivers in Windows 10 (Also booted outside of Unraid and pre-installed the drivers, but they take no effect in the VM)
I am getting the following in the VM log:
2019-07-31T09:48:52.886459Z qemu-system-x86_64: vfio_region_write(0000:2d:00.0:region3+0x14290, 0x67ab0e0d,8) failed: Device or resource busy
Seems that unraid isn't fully releasing the card so far as I can tell, my only thought would be running unraid truely headless with no gfx at all, so it has no ability to interfere with the card, but don't know if that's possible, and of course there is no way to diagnose then if you have no network. Also FYI I am booting the VM directly from the NVMe drive, with no vdisks.
I have attached my VM XML to save the length of my post
Win10.xml
