VMWare Workstation [0] (and I thought VirtualBox - though I can't find any official docs [1]) should be able to use the Hyper-V hypervisor via WHP.

QEMU can also use WHP via --accel whpx.

As a network engineer I mainly like VMware workstation because of its awesome virtual network editor that lets me easily build complex topologies but it doesn't work when you use Hyper-V.

It works indeed, but the performance drop is quite drastic.

Same. Have to disable VBS for VirtualBox, and it gets more and more obscure with each update because some features like Windows Hello force it back on.
