Virtualization Intel VT-xEPT it not supported on this plataform.

I currently have one of Dell's most powerful notebook, an E7300 latitude with Intel i7-8665U processor, 32 GB of memory and 512 SSD disk.

I bought the latest version 16 of VMWare Workstation to run on this machine with Windows 10 Pro. I need to install Hyper-V on a Windows Server 2019 Virtual Machine with Nested Virtualization.

All BIOS virtualization options are already enabled. I mark the option "Virtualize Intel VT-x/EPT or AMD-V/RVI" in the VM processor properties. But when trying to connect the virtual machine I get the following message :

"Virtualized Intel VT-x/EPT is not supported on this plataform. Continue without virtualized Intel VT-xEPT?

I can't believe this machine doesn't support this.

I think the Windows 10 Professional in your host laptop has Hyper-V enabled and VMware Workstation 16.x is thus using the User Level Monitor (ULM) instead of the root VMM.

https://blogs.vmware.com/workstation/2020/05/vmware-workstation-now-supports-hyper-v-mode.html

You should turn off the Hyper-V feature at the host OS and the root VMM will be used and nested virtualisation for Workstation Pro should work like it has before even version 16.

I also have this issue.

My specific circumstances are Workstation 16 on Windows 10 Pro with WSL2 enabled (which I need, so can't disable Hyper-V).

I then want to run nested virtual machines using ESXi 6.5 through Workstation and I get a warning that the EPT feature on the CPU is not allowed to be enabled or not supported. If I disable it on the CPU tab of the VM, ESXi virtual machine does install but I am only allowed to have 32bit VMs that are nested.

The article you posted seemed a bit confusing - is it saying that if you had Hyper-V enabled in situations where prior to WS 15.5 you couldn't have Workststion installed/working whatsoever, but now you can - but the caveat being that you can't do what I'm trying to do?

Thanks!

Michael.

Yes, prior to version 15.5.5 and 16, Workstation Pro/Player would not run with Hyper-V installed.

But it looks like this situation is you can't have your cake and eat it, too.

Indeed - it seems so. Do love a bit of cake though.

Thanks for the reply - I can probably get round this by not nesting. Cheers.

Spoiler
 

I have Lenovo X1 Extreme with Intel i7-9750H processor, 32 GB memory and 512 SSD Disk.

 

 

I had the same issue and after spending few hour and troubleshooting, I managed to resolve this issue.

 

Step 1

Enable your Virtualization

Step 2 - Turn off Hyper V and untick Virtual Machine Platform in Windows 10 Host Machine

Step 3 - Type command in PowerShell (Runs as Admin)

 Step 4 - VMware Workstation Pro 16

Tick Mark - Virtualize Intel VT-x/PT

 Step 6 - MOST IMPORTANT

Option - Version need to Hyper- V (unsupported)

 Once you installed Hyper V, Restart the Virtual Server. Then you will see Hyper V in Tools.

Hi there,

Also Last step is to Disable Turn on virtualization Based Security

Go to Local Group Policy Editor, Computer Configuration, Administrative Templates, System, Device Gaurd

Disable Turn On Virtualization Based Security.
