Hi, I try to passthrough a GTX 550 ti or a GTX 750 ti to a Windows XP VM. Doesnt matter if I passthrough to a XP VM or a Windows 7 VM. Everytime Error Code 10 in device manager for the display driver. A little bit confusing is, that the Audio device hasnt any error code.

Could anybody help me? Dont be confused why I tryed XP and 7. Its because I wanted to know if the problem ist the Uefi setting for passthrough PCIe.


Hardware:
I7 3770
32GB DDR3 1333MHz
1x AMD RX 570
1x GTX 550 TI or GTX 750 TI
Asus P8Z77-V (Bios Settings: IGPU first CSM enabled, Intel virtualization enabled, Memory Remap Feature (VT-d) enabled)
Samsung Q860 1TB SSD
PVE 8.0



What I have done:



in /etc/default/grub

Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction video=vesafb:off video=efifb:off video=simplefb:off"

Code:
update-grub





/etc/modules

Code:
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd



/etc/modprobe.d/vfio.conf (one ID the RX the other GTX 550 TI)

Code:
options vfio-pci ids=1002:67df,1002:aaf0,10de:1244,10de:0bee disable_vga=1



/etc/modprobe.d/iommu_unsafe_interrupts.conf

Code:
