Nested Virtualization with Hyper-V and VMware

Question

So I'm running Windows 11 Pro on a AMD RYZEN 9 5950X with Hyper-V, Windows Subsystem for Linux 2, Windows Subsystem for Android, Virtual Machine Platform, Windows Hypervisor Platform, and VMware Workstation Pro. I'm trying to enable Virtualization Intel VT-x/EPT or AMD-V/RVI however I get this error "Virtualized AMD-V/RVI is not supported on this platform. Continue without virtualized AMD-V/RVI?". I am being told that I need to disable Hyper-V however I need that for WSL2 and WSA. I was under the assumption that Windows 11 added support for Nested Virtualization for AMD CPUs as it wasn't available in Windows 10. Is there something I am missing about how this works?

Answer 1

@Ian Xue (Shanghai Wicresoft Co., Ltd.) it is not a VMWare WS issue. I am running into the same problem. CPU-Z reports that there is no VT-X flag enabled even though in bios both VT-X and VT-D are enabled.
It's clearly an windows issue because if I boot under linux I have both flags enabled.
So, that being said. What options do we have? Besides, well, not using Windows?

After I disabled everything related to virtualization, including WSL, I got the VT-x flag that I was missing and VMWare identifies it accordingly.

And this is from a VM that runs in vmware on the same windows host.

Answer 2

Hi,

Since this sounds more a VMware workstation issue, you'd be better off asking it in the VMware forum for better help.

What is the version of your VMware workstation? I found that it supports hosts with Hyper-V enabled since 15.5.
