Hi I am running Proxmox VE 6.4-6 in one of my old desktop with the following configuration.
MSI Motherboard: H310M PRO-M2 (MS-7B28)
Processor: Intel i5 - 8600K
GPU: GeForce GT 710B
I have enabled Intel VT-d from motherboard.
I am running few VMs and one of them is a Kali linux box. I am trying to passthrough my GPU so that I can use to to do password cracking (with hashcat)
I have updated GRUB (content pasted bellow)
I have added kernel modules (content pasted bellow)
I have added GPU drivers on the blacklist (content pasted bellow)
I created a Kali VM (content pasted bellow)
The issue is
1. The GPU is still attached to host. I have a monitor plugged in to the GPU card. When I reboot/start, I can see boot process on the monitor and then stays on login screen (where it shows the IP and port to connect from a browser). As I understand, since I have added NVIDIA driver to the host's blacklist. There should not be any display from the host on the monitor. Please correct me if I am wrong.
2. When I start my Kali VM, it won't start and will throw error saying that IOMMU not present. If I remove the PCI device from VM's hardware list then the VM starts normally.
This is what my iommu groups look like

Please let me know what I am doing wrong here. I do not want my GPU to be used as a display, it is just for computation.
Thank you.
