Windows 11 Q35-7.1 with OVMF TPM and Radeon 6600xt passthrough Won´t start

[Veriz]

Hi, 

 

Im new to Unraid and just built my first Unraid Host.

IT is running on a Asus Prime Z690-A, uefi boot for unraid, resize bar disabled, not Fastboot, IOMMU enabled from start all virtualization extensions enabled.

CPU: Core i9-12900KF

memory: Dominator ddr5-5200

AMD Sapphire Radeon 6600XT

 

I previously had a dell T620 running Ubuntu with 2 Raid-z pools.

Now im trying to consolidate NAS/Gaming/Lab into one machine.

 

I´ve read some articles in this forum about passthrough and think i´ve done the setup correctly.

 

Install windows 11 from ISO, installed Virtio drivers. Then when i try to passthrough the 6600xt and associated sound device it won´t boot. if i run virtual graphics with VNC console it runs, but when i try to passthrough the 6600 card the logs says device is busy.

I have done the passthrough the "new" way using tools, system devices, selected both iommu groups and bound them at boot.

 

i also tried it the old way but same result.

 

When i tried using the i440 Bios i can´t get through the windows 11 setup, screen goes black after naming the OS.

The error i get in logs are this: 2022-12-05T13:28:54.125767Z qemu-system-x86_64: vfio_region_write(0000:03:00.0:region0+0x9ef90, 0xff000000ff000000,8) failed: Device or resource busy

Even tried Windows 10 VM with Q35-7.1 and gpu passthrough. doesn´t feel like Unraid has let go of the device properly, Any help would be greatly appreciated

Did U fix? If not, I'd suggest have a look at your settings again (maybe your stubbing, your CPU isolation/pinnings), your BIOS settings. I've been away from unRAID for 2 years and just come back and I can see weird stuff in the logs any one of which could be the issue).
