I tried to Install nvidia driver on a VPS with these features:

System info:

• Ubuntu 22 Server
• VmWare VPS (14 core CPU) (24GB of RAM)
• Nvidia driver 520
• GPU RTX 3060

The Problem:

After OS reboot nvidia-smi shows GPU correctly but when I try again it returns No devices were found.

Installation Steps:

/etc/modprobe.d/blacklist-nouveau.conf >>

blacklist nouveau
options nouveau modeset=0

sudo update-initramfs -u
sudo reboot

Remove Intel Microcode

sudo dpkg -l | grep intel
sudo apt purge intel-microcode
sudo update-grub

Then add

hypervisor.cpuid.v0=FALSE to VM Configuration Parameters

Install development tools for build Nvidia driver

sudo apt update && sudo apt install gcc make  build-essential libglvnd-dev pkg-config

Install Nvidia Driver from .run file:

sudo init 3
chmod +x NVIDIA-Linux-x86_64-520.56.06.run
./NVIDIA-Linux-x86_64-520.56.06.run  -m=kernel-open

Install without kernel signing
Then:

/etc/modprobe.d/nvidia.conf >>

options nvidia NVreg_OpenRmEnableUnsupportedGpus=1

Then reboot.

How can I troubleshoot system errors?
Is there any missing thing?
