Every time I run my VM with VT-x and Hyper enabled I get this error, "Virtualized Intel VT-x/EPT is not supported on this platform." then it asks to continue with disabling VT-x.
This is very strange because now VMWare 16 now has support to work alongside Hyper-V but I'm not able to run any of my machines with VT-x enabled along with Hyper-V. I tried to do a complete clean re-install and tried with new VMs but still no luck.
My configurations:
Windows 10 Pro, 64-bit (Build 19041.329) 10.0.19041 (Version 2004)
VMWare 16.0.0 build-16894299
It looks like you can have cake but won't be able to eat it.
Starting with 15.5.x, a User Level Monitor (ULM) is used instead of the root VMM.

If Hyper-V is uninstalled from the Windows host, the root VMM will be used and nested virtualisation will be back to the way it was in previous versions with the root VMM.
Did you install Windows Hypervisor Platform?
