Hi, unfortunately I have this problem with my Tesla K20Xm, I ran the passthrough on my HP DL380p Gen 8 server with the latest Proxmox 8.1.4 patches on board, once passed the guest device detects it and once the drivers are installed it gives me this problem appears on win 10 device manager:


[The device could not start. (Code 10)

Insufficient system resources to complete the API.],



I don't understand why this thing happens, I've tried everything, I attach the configuration of my vm:

this is my grub configuration:





GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on vfio-pci.ids=10de:1021,10de:097d iommu=pt nox2apic intremap=no_x2apic_optout video=efifb:off,vesafb:off,simplefb:off"


I added it here later vfio-pci.ids=10de:1021,10de:097d and also other modules I tried taking them off and putting them on.









this is the configuration of vfio.conf:



options vfio-pci ids=10de:1021,10de:097d disable_vga=1










these are the blacklisted modules:



blacklist nouveau
blacklist nvidiafb
blacklist nvidia*
blacklist i915







this is the configuration of "/etc/modprobe.d/iommu_unsafe_interrupts.conf":



options vfio_iommu_type1 allow_unsafe_interrupts=1





questa è la confiurazione di "nano /etc/modprobe.d/kvm.conf":



options kvm ignore_msrs=1 report_ignored_msrs=0


If you can help me I would be truly grateful

Good Day
