HVF is a para-virtualized QEMU accelerator for macOS based on Hypervisor.framework (HVF). Hypervisor.framework is a thin user-space wrapper around Intel VT/VMX that enables to run VMMs such as QEMU in non-privileged mode. The unit tests can be run on macOS to verify completeness of the HVF accel implementation.
