Dynamically managing a serial port interface connected to a direct console user interface (DCUI) of virtualization software using headless flags

A computing device executing virtualization software, the computing device comprising:

• a hardware serial port;
• a memory having a program for managing a serial port interface of the virtualization software to the hardware serial port;
• and
• a processor configured to execute the program to:
• initialize a serial port interface of a host device;
• examine a headless flag to determine if the host device is headless, wherein a headless device is a device that does not support direct connection to a physical human interface device;
• and
• if the headless flag is set, set one or more serial port options to a default value, wherein a first serial port option connects a direct console user interface (DCUI) service to the serial port interface.

A non-transitory computer-readable storage medium comprising instructions, which when executed in a computer system, causes the computer system to carry out a method of managing a serial port interface of virtualization software executing on a host device, the method comprising:

• initializing a serial port interface of the host device;
• examining a headless flag to determine if the host device is headless, wherein a headless device is a device that does not support direct connection to a physical human interface device;
• and
• if the headless flag is set, setting one or more serial port options to a default value, wherein a first serial port option connects a direct console user interface (DCUI) service to the serial port interface.
