COMPUTER SYSTEM FOR CONTROLLING VIRUAL MACHINES

摘要

A computer system for controlling virtual machines each given a different identification number. The system comprises mask registers and I/O interruption queues, each provided with the same numbers as the virtual machines, and corresponding to any one of the identification numbers. An interrupt handling in any one of the virtual machines can be carried out directly by using a pair of corresponding mask registers and I/O interruption queues without an interposition of the VM monitor.
