Hi,
I followed this tutorial: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/
But my VM does not display the login prompt and I can connect via SSH without any problem.
I would like to know why the prompt is not displayed ?
If I disable passthrough, I get the prompt that appears
/etc/default/grub
/etc/modules
dmesg | grep -e DMAR -e IOMMU
lspci -nnv |grep VGA
/etc/pve/qemu-server/100.conf
Anyone have any ideas?
Thanks
