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.
