Abstract:
Arbitrary, unmodified code and/or software may be executed directly on a host processor operating in a virtualized mode using hardware virtualization support and performance counters. The arbitrary software may be run on the host processor until the host processor exits from the virtualized mode. An end execution time may be calculated in response to the host processor exiting from the virtualized mode. An event may then be handled based on an execution time at which the host processor exited from the virtualized mode and a time at which a scheduled event was to occur.
