The LoadMaster expects a serial port connection. However, not having a serial port connection does not cause problems, other than causing the following log message:

agetty##: ttyS0: ioctl: Input/output error

To prevent these errors from appearing in the logs, enable a virtual serial port on Nutanix AHV by following these steps:

  1. Turn off the VM.
  2. SSH into one of the Controller VMs (CVMs) in the AHV cluster.
  3. Run the following command to add the serial port to the VM:
acli vm.serial_port_create <VMName> type=kServer index=0

Replace <VMName> with the name of the VM.
