Abstract: A host computer for virtualizing a target multicore processor includes a host CPU and a host memory storing a virtual time object and a VM, the VM including target code. The host CPU executes the plurality of threads in parallel on corresponding virtual cores, including a first thread executing on a first virtual core and a second thread executing on a second virtual core. The VM assigns a designation to the first virtual core to increment the virtual time object by a first count of a first plurality of instructions executed in the first thread over a first duration. The VM moves the designation to the second virtual core in response to detecting an event that defines an end of the first duration. The second virtual core increments the virtual time object by a second count of instructions executed in the second thread over a second duration.

Abstract: A method, apparatus, and virtual computer system for testing application software. A first operating system of a first operating type is run on a first processor of a first processor type in a physical computer system. A virtual machine that emulates a second processor of a second processor type is run on the first processor. A second operating system of a second operating type is run on the virtual machine with the virtual machine running on the first processor. The first processor running the first operating system and the virtual machine running the second operating system together form the virtual computer system. A tool qualifier module performs verification of an application testing tool on the virtual machine using tool qualification data to qualify the application testing tool before the application testing tool is run using the second operating system on the virtual machine to test an application program.
