Access the VM console on Proxmox Virtual Environment (PVE)

Connecting to the LXC (CT) console is straightforward; simply use the command: pct enter <container_id>.

However, connecting to a VM console requires a few additional setup steps beforehand.

The process is below:

1. Ensure Serial Console is Configured:

   • Add a virtual serial port to the VM.

     qm set <vmid> -serial0 socket

   • Replace <vmid> with the ID of your virtual machine.

2. Adjust Console Configuration:

   • Ensure the VM uses a serial terminal as the display output.

     qm set <vmid> -vga serial0

   • This configures the display to use the serial port for terminal output.

1. Start the VM:

   • If the VM is not already running, start it using:

     qm start <vmid>

2. Access the Console:

   • Use the following command to enter the QM console:

     qm terminal <vmid>

   • This will open a serial terminal interface for the VM.

1. Exit the Console:

   • To exit the console, press Ctrl + O.

This method works if the VM has been configured with a serial port. If encounter any issues, ensure the serial console is properly set up within the VM's configuration.

1. Bash Script to Create a VM with Serial Terminal Display and Testing Serial Port

Here's a Bash shell script to create a virtual machine that sets the serial terminal as the display and adds a serial port to the machine for testing purposes.
