ABSTRACT:
A virtual machine user gains access to the entire address space of another virtual machine operating system by storing and executing a machine code program in the other virtual machine that gives the monitoring machine user access to the desired data control structures in the target address space. This machine code program is executed in the target virtual machine after the initial program load (IPL) of an operating system in that virtual machine. In addition, access is gained to the execution space of the host operating system under which the monitoring virtual machine itself is supported by using system maintenance commands to set appropriate system operating parameters that permit viewing the control data structures of the host machine supporting the virtual machine user.
