Good day everyone. So just updated my system to version 7.0.0 And now the AMD pass thought is no longer working. I get the following: 2025-01-14T00:48:50.730413Z qemu-system-x86_64: vfio: Cannot reset device 0000:03:00.1, no available reset mechanism. I tried to uninstall the AMD Vendor Reset plugin and then reinstall. Still no success. Any ideas? Cheers,

Thank you Simon for the tip, you did find the magic trick. Installed the AMD Reset Plugin and its working great for me. Running on unraid 7.0.0-rc2. cheers

Enjoying unraid, but encountering some issues with GPU Passthrough to VM. Message from libvirtlog: 8616: error : virHostdevResetAllPCIDevices:601 : Failed to reset PCI device: internal error: Unknown PCI header type '127' for device '0000:07:00.0' So basically I have 2x AMD Radeon RX 5600 XT in my Tower. (Which I want to Passthrough virtual machines) IOMMU Groups: - made sure I split them, ended up with PCIe ACS override=Both (VM Manager) - selected them and Bind Selected to VFIO at Boot (System Devices) VM Assignment: - created a Windows 10 VM and assigned the Graphics card, also assigned the matching sound card (0000:03:00.0) - created a Ubuntu 24 VM and assigned the Graphics card, also assigned the matching sound card (0000:07:00.0) Everything was working fine. (rebooted the vm a couple of times, did updates, etc...) - Then decided to install the AMD drivers after install cannot boot the vm, get Execution error internal error: Unknown PCI header type '127' for device '0000:07:00.0 - Also noticed, even without installing the AMD drivers in the vm, after a while would get the same results - This was all done on unraid 6.12... just recently upgraded to unraid 7.0.0-rc.2 with same results - Basically a reboot of the system fixes it until this happens again (failing to reset pci device) Any assistance would be much appreciated. I am sure there must be a magic trick for this.
