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.
