Abstract
A data processing system operated with multiple levels of virtual machine guests under a host control program. The second level of guests are invoked, operated, and terminated without host intervention, as has been required in prior systems, to significantly increase the operating efficiency of the system. Address translation is done by providing machine capability to translate second level guest addresses to real memory addresses taking advantage of the first level guest being located at a simple offset within real memory. Special facilities for second level guests periodically test for timing interruptions for second level guests and update the second level guest timing facilities.
