1. A computer program product for prioritized hardware thread scheduling, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising: responsive to identifying a latency sensitive workload, activating, by an operating system, one or more hardware threads from an idle state to meet dispatch latency demands for the latency sensitive workload; avoiding delays due to hypervisor dispatch latencies by preventing the one or more activated hardware threads from performing hypervisor virtual partition switching; and responsive to completing the latency sensitive workload, deactivating the one or more activated hardware threads and returning them to the idle state, wherein the one or more hardware threads in the idle state seek other latency sensitive workloads in a local run queue associated with the one or more hardware threads in the idle state.
