A system, method, and program product is provided that automatically allocates a display screen into two areas when the display screen is pivoted from a landscape orientation to a portrait orientation. A hypervisor receives a pivot request (e.g., from a user) to pivot the display screen from a landscape orientation to a portrait orientation. When the display screen is oriented in the landscape orientation, a primary operating system displays its data on the display screen. Upon reception of the pivot request, the hypervisor allocates the display screen into a primary display area and a secondary display area. The hypervisor then displays data originating from the primary operating system in the primary display area and displays data originating from a second operating system in the secondary display area.
