Abstract
Restoring access to running states of multiple primary computing systems onto a single computing system. The captured running states each include, or are altered to include, at least one device driver that is configured to interface with a common virtualization component that runs on the single computing system. The common virtualization component is configured to at least indirectly interface with hardware on the single computing system. The hardware potentially operates using a different interface than the device driver is configured to interface with. The system identifies a boot order for each of the primary computing systems, and then starts the running states for each of the primary computing systems in the appropriate boot order in a manner that takes advantage of the virtual environment exposed by the single computing system.
