  • [7.0.0beta2] VM bluescreen ACPI_BIOS_ERROR with GPU passthrough

    Maor

    By Maor

      • Minor

    I have taken an old unraid flashdrive and upgraded to latest v7beta2 and moved to a new HW platform.

    I have Minisforum BD790i + RTX3090 and want to make a windows VM with the GPU. I have enabled SR-IOV, IOMMU and SVM in the bios.

    VM without GPU seem to work just fine. When I add the GPU it throws bluescreen with "ACPI_BIOS_ERROR"

     

    I would highly appreciate help with figuring out what is causing the bluescreen

    The issue has already been identified and a fix has been put in for the next release.

     

    Go into the XML editor and cahnge the bus numbers to be 0x07 from 0x021 to see if that resolves your issue. Dont change the source values.
