Method and system for tracking data correspondences

摘要

One embodiment is a method for tracking data correspondences in a computer system including a host hardware platform, virtualization software running on the host hardware platform, and a virtual machine running on the virtualization software, the method including: (a) monitoring one or more data movement operations of the computer system; and (b) storing information regarding the one or more data movement operations in a data correspondence structure, which information provides a correspondence between data before one of the one or more data movement operations and data after the one of the one or more data movement operations. The “monitoring” may comprise monitoring data movement at one or more of an interface between the host hardware platform and the virtualization software, and an interface between the virtual machine and the virtualization software.
