Abstract

A computer system having a chief system control program running in a real machine as a host where the host controls standard system control programs (SCP's) and controls virtual machines (Domains) called guests. Guests operate with interpretive execution as second-level guests. Control is transferred from a second-level guest to the guest SCP or to the chief SCP with only one control interception. Control is transferred directly between the second-level guest and the Chief SCP bypassing the first-level guest.
