    Intel i7-6700 and HD530 passtrough with audio

    in VM Engine (KVM)

    Posted · Edited by coder

    Just for a bump, if anyone has a thought what else i can try?

     

    EDIT:  i found the solution from the forums. First i needed to add some RAM, with 5GB the VM started, no video issues, Intel drivers installed, audio is working - so all good!

    The VM had some massive memory usage, over 90% was in use with no simple reason. Then i found solution for the RAM issue:

    It solved the RAM usage problem.

    VM shutdown/restart crashes Unraid itself with GPU HD5450 passtrough

    in VM Engine (KVM)

    Posted

    I cannot figure out why the VM shutdown/restart crashes Unraid itself.

    M/B: Gigabyte Technology Co., Ltd. H110TN Version x.x - s/n: Default string

    BIOS: American Megatrends Inc. Version F24. Dated: 12/14/2017

    CPU: Intel® Core™ i7-6700T CPU @ 2.80GHz

    HVM: Enabled

    IOMMU: Enabled

    GPU HD5450

     

    IOMMU group 13:[1002:68e1] 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Park [Mobility Radeon HD 5430]

    [1002:aa68] 01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cedar HDMI Audio [Radeon HD 5400/6300/7300 Series]

     

    Picture over HDMI and audio work good, but every time a restart/shutdown the VM inside the Windows 10 OS itself, it halts/crashes the Unraid OS. Also after that i manually have to enable VM manager!

     

    I tried Windows 10 VM with different combinations:

    Memory 4  and 8GB

    OVMF does not work at all, i  think because of HD5450 does not support Uefi, so only SeaBIOS works

    i440fx-3.1 and Q35-3.1

     

    What am i missing?

    So with this line in Syslinux config, i was able to boot my Windows 10 VM, but after installing Intel HD graphics drivers, i get Code 43 at device manager, also audio is not working, but shown in the VM.

    append pcie_acs_override=downstream vfio-pci.ids=8086:a170 modprobe.blacklist=i2c_i801,i2c_smbussnd_hda_intel video=efifb:off,vesafb:off

     

    Also in the VM logs:

    2019-09-08T10:47:13.195190Z qemu-system-x86_64: vfio: Cannot reset device 0000:00:1f.3, no available reset mechanism.

    As in this thread suggested, i added "append pcie_acs_override=downstream vfio-pci.ids=8086:a170 modprobe.blacklist=i2c_i801,i2c_smbus initrd=/bzroot" to Syslinux config i Unraid OS.

     

    But when i create Windwos 10 VM, i cannot get even the GPU passtrough to work - no display over HDMI.

     

    So can somebody help me, like with what settings should i try to create this VM  - machine/BIOS version? 

    Hyper-V is set to no.

    Graphics card is shown correctly: Intel HD Graphics 530

    Also the sound card is detected as: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller

     

    VM with Q35-3.1 and OVMF bios gives an error of:

    VM with i440fs-3.1 and SeaBIOS bios gives tons of errors with: 

    2019-09-07T16:20:18.710157Z qemu-system-x86_64: vfio_region_write(0000:00:02.0:region2+0x1788, 0x0,4) failed: Device or resource busy

     

    SeaBISO with i440fs-2.7 the VM picture is shown, but only if i do not mount the OS Install ISO!
    When the iso is mounted it gives erros:
    2019-09-07T16:36:16.614679Z qemu-system-x86_64: vfio_region_write(0000:00:02.0:region2+0x1a4424, 0x0,4) failed: Device or resource busy

     

     

    NB! if somebody can help me to get it to work, i´ll be willing to do a BEER/Coffee donation via PayPal! 😉
