Virtual COM console function

 Overview of Virtual COM console function
The conventional system console can select and operate one of the LPAR manager
screens and guest screen. The virtual COM console can use a higher-speed console than
the normal serial console for each LPAR with the serial over LAN function of the LPAR
manager. Concurrent operation of multiple LPARs enabled the operating guest screens
by using the virtual COM console instead of the system console. Up to 16 LPARs can be
simultaneously connected to the virtual COM console.
