Maintenance mode is not available on virtual machine version 11 and above Technical Level
  • On virtual machine version 11 and above, there is no option to enter maintenance mode.

This issue occurs when the user creates a new VM on VMware ESXi server version 6.0 and above, as the default virtual machine version is 11.

If a user chooses to create virtual machine on version 11, the serial device is not automatically created.

It must be added manually, when the VM is powered off.

Add to VM Hardware:

Device type = 'serial port'
Serial port output ='Use physical serial port'


VMWare Example

Note: The VM must be powered off for the serial port to be added.
