This might be a boon at my work, where I need to use vagrant and I would also like to use docker workstation on my way Windows machine at work. work mandates that we run on Windows or Mac and most of my colleagues weren't run on Windows so it's important that we be able to run both things on Windows.
I'm not sure why the submitter felt it necessary to edit the original title, "VMware Workstation 15.5 Now Supports Host Hyper-V Mode", but that one is both more specific and more accurate.
Also, I may be wrong but it sounds like this applies only to "Workstation Tech Preview 20H1", for now.
Just a note that I think could be important for someone here, the nested virtualization is not currently supported. What this means ? You will not be able to run another hypervisor inside the guest vm.
