VM Windows with GPU nVidia Quadra on HP Gen 8

[argon]

hello everyone, I have a problem on an HP Microserver Gen 8 with VM Windows + GPU nVidia Quadro.

IOMMU Group 11 07:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK107GL [Quadro K600] [10de:0ffa] (rev a1)
IOMMU Group 11 07:00.1 Audio device [0403]: NVIDIA Corporation GK107 HDMI Audio Controller [10de:0e1b] (rev a1)

grub : GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1 append pcie_acs_override=downstream"
/etc/modules : vfio vfio_iommu_type1 vfio_pci vfio_virqfd

vm.conf : hostpci0: 07:00.0;07:00.1,x-vga=1,pcie=1

qm start : vfio-pci 0000:07:00.1: Device is ineligible for IOMMU domain attach due to platform RMRR requirement. Contact your platform vendor.

I don't need the nvidia hdmi audi how to disable just 07:00.1 ?

Thank you for your help

Device is ineligible for IOMMU domain attach due to platform RMRR requirement. Contact your platform vendor.

this means that your motherboard needs either a bios update, or in absence of this, you would need another mainboard

ok thanks fo your answer. I disable successfully the nvidia hdmi audio with this command :

echo '1' > /sys/bus/pci/devices/0000:07:00.1/remove

now the VM start and works !

But another problem, start with 2GB Memory but got timeout error with 4GB Memory.
Another VM Windows 7 without graphical accelerator start with 4GB Memory

I tried with and without ballooning, same error.
