Hi everyone, I'm asking for help here after hours of trying and following guides, but nothing helps.
I'm trying to pass through to a GTX 1060 on an HP ML350 Gen9 - This installation of PVE is new, currently just for testing, so I know the hardware before I install this server fully
Proxmox 8.4.1 - Kernel 6.8.12-11-pve
After I pass through to a Windows VM, I install the NVIDIA driver. After the installation, everything looks fine, but I still don't have a display from the GPU, so I reboot the VM, and then the famous code 43 appears!
It always appears after a restart after installing the drivers, no matter if I choose x-vga=1 or not.
Things I tried *not exactly in this order*
Reinstalling Windows several times after changing settings in the host
Create a new VM
Change the processor model in the VM
Change the version of the Machine to 9.2, 7.1, 8.2
Try changing settings in vIOMMU
Try the PCI Device settings - with/without All Functions, With/without PCI-Express, With/without ROM-Bar
I also tried changing the OS type to Linux
I tried other drivers from NVIDIA's website - the newest and the oldest they have on the site
I tried adding a ROM file - I downloaded the match version from TechPowerUp
I tried changing the kernel host version to 6.5
I also tried configuring vGPU with the scripts and guides that are available online -
But there is always a problem installing the NVIDIA drivers on the host, so I didn't get too far with it
And nothing helped!! Still code 43 after restarting after installing the drivers
But! And this is very important
I tried to install in a new Ubuntu VM. After installation, I pass the GPU
Without checking the Primary GPU, the VM recognized the card
I installed the drivers
Still no screen
I shut down the VM, then checked the Primary GPU, started the VM, and suddenly I had a screen with Ubuntu and everything seemed to work properly!
So something is not working with Windows, and I can't figure out why!!
My current host settings
Yes, I know that after kernel 6.5, "intel_iommu=on" isn't necessary, but I tried anyway.
