Workstation 16 Pro Error "Virtualized Intel VT-x/EPT is not supported on this platform

I just upgraded to Workstation 16 Pro as it said it would work with Hyper-V, and I want to run docker desktop.

However I am getting the error:  "Error "Virtualized Intel VT-x/EPT is not supported on this platform".  Every time I search it I get the result of "disable hyper-v", but I just spent a bunch of money to be able to run this with hyper v.

The thing I am trying to run is Cisco Modeling Labs (CML): a VM that spins up VMs of routers/switches/etc.

Hi,

As you're mentioning Hyper-V, your host OS must be windows.

Not all versions of Windows however are supported for this to work and this might be what you are running into.
AFAIK, this only works on Windows 10 and the minimum version of Windows 10 is 20H1 build 19041.264 or newer.

The exact system requirements can be found here:
https://docs.vmware.com/en/VMware-Workstation-Pro/16.0/com.vmware.ws.using.doc/GUID-177F1E77-BFFD-48...

edit: Wait.. oh dear. I now realize that I might to be misreading it.

The above requirements are for being able to run a guest OS in VMware Workstation while Hyper-V is enabled at the host OS.
This does NOT allow you to run a guest OS in your VM itself. The only way to run a nested VM is to disable the Hyper-V role on the host OS where you run VMware Workstation. In that scenario nested VMs work fine and you can even run Hyper-V in your guest OS.


Hope this helps,

moderator: Moved the thread to VMware Workstation Pro discussions. Your question is indeed about nested virtualization, but the discussion area where it was posted was specific for vSphere. You're likely to get better answers here.

Unfortunately, Hyper-V API does not allow for nested virtualisation – the only way to use that is to disable Hyper-V on the host and let Workstation use its own virt.

This host supports Intel VT-x, but Intel VT-x is disabled.

Intel VT-x might be disabled if it has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting.

(1) Verify that the BIOS/firmware settings enable Intel VT-x and disable 'trusted execution.'

(2) Power-cycle the host if either of these BIOS/firmware settings have been changed.

(3) Power-cycle the host if you have not done so since installing VMware Workstation.

(4) Update the host's BIOS/firmware to the latest version.

This host does not support "Intel EPT" hardware assisted MMU virtualization.

VMware Workstation does not support the user level monitor on this host.

Module 'MonitorMode' power on failed.

Failed to start the virtual machine.
