Abstract

See full text

A peripheral system attached to a host having plural virtual machines accommodates the virtual machines via 'guest' attribute signals signifying that a given chain of peripheral or I/O commands are virtual machine sourced (GO bit). The attribute signals may include modifier control signals to enable the peripheral system to adjust to virtual machine operations of the host. In particular, virtual machine 'minidisks' are accommodated.
