Gentlemen,
My apologies for the delay in the investigation.
@PragmaticPraxis, according to the technical report your virtual machine is located on the external USB 2.0 disk (WD Passport). If yes, then we strongly recommend you move the VM to the internal Mac disk. USB 2.0 I/O bandwidth is not enough to handle VM disk operations properly.
@RodB, The Apple hypervisor was indeed added in Parallels Desktop version 12 as an optional (I would say even experimental) hypervisor driver. Apple hypervisor comes short of the following matters comparing to the Parallels hypervisor:
- Performance: slower on VM startup and shutdown
- Stability: may crash more frequently
- Functionality loss: no PMU, nested virtualization, thermal monitoring, energy profiling
Parallels Hypervisor is the best one.
Please try to reduce the number of CPUs to 2 and set 4096MB of vRAM to the virtual machine. Please let me know if this helps.
