I tried to passthrough my GPU to a Windows 10 VM so I can use it for gaming. The GPU shows in device manger with error code 43 and when I try to install the Nvidia drivers approximatly where the screen would go black for a sec on a normal PC RDP loses connection and after it reconnects 10 seconds or so later the drivers are not installed and a critical error stating that Windows has unexpectatly rebooted shows in eventviewer, also no BAR3 error in the syslog. I also tried Win11, but it did not do better.
Kernel version:
Linux 5.15.102-1-pve
Specs:
Intel I7 7700
Asus H110M-R
Asus GTX 1080 Turbo (has a monitor plugged in)
My current config:
enabled VT-D in the Motherboard
GRUB:
.conf of the VM:
modules in /etc/modules:
I used these commands for interrup mapping:
I blacklisted the drivers in /etc/modprobe.d/blacklist.conf
option in /etc/modprobe.d/vfio.conf:
I got the .rom from Techpowerup and installed the VirtIO vioscsi, NetKVM and Balloon drivers
thats just my current config, I already tried a lot of different stuff, especially in the .conf file
