On the Vmware Workstation comparison page
It talks about Hyper-V Support.
Can somebody explain what this means. I was under the impression that you cannot use Hyper-V and VMWare workstation on the same machine?
I searched the documentation and could not find a reference (unless I missed something here).
That's marketing at their best , I'm surprised they tout Hyper-V support at the 2nd point in the list even.
You are absolutely correct that you cannot enable the Hyper-V role on a host and then install or run VMware Workstation. It will not work (at all).
You can however enable Hyper-V in a guest and use Hyper-V while running under Workstation.
This probably will require you to change the guest OS on that VM to Hyper-V in order to work reliable.
Note however that your Hyper-V guests performance as nested VMs (running as guests within your VM) will not be optimal.
