[pve-devel] Fixed not working pci_dev_reset for vfio devices

[Kamil Trzciński]

MB: ASUS H81M-E (with integrated graphics)
GFX: GeForce GTX660

I also use this patch for qemu:
https://github.com/ayufan/pve-qemu-kvm-with-vfio/commit/afee03e8739cf9ee78408bec9a62cf5c558860f9

And this patches for kernel:
https://github.com/ayufan/linux-kernel-with-vga-passthrough/commits/vfio

grub.cfg:
GRUB_CMDLINE_LINUX="intel_iommu=on"

modules + initramfs:
kvm ignore_msrs=1
pci_stub ids=10de:11c0,10de:0e0b,8086:0412,8086:0c0c,8086:82c0

And my lspci:
00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell
Integrated Graphics Controller [8086:0412] (rev 06)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device
[10de:11c0] (rev a1)
01:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:0e0b] (rev a1)
