We had similar issues getting FreeBSD SMP working under ESXi ARM Fling. In that instance, there were bugs in both the hypervisor as well as in FreeBSD. With the FreeBSD kernel fixes, I tested those on Parallels last night, but still no go with SMP. There is possibly more work to do in the kernel, but may also be some bugs in the hypervisor as well. For ESXi ARM Fling, the issues all revolved around the GIC (Generic Interrupt Controller) and the way inter-CPUs communication happened. If memory serves me correctly, one CPU core was waiting on another CPU core to finish initialization and report back in a "ready" state so to speak. Where Parallels with FreeBSD is hanging, and how it is hanging, looks virtually identical from my very limited testing last night.
