VMware Workstation does not support nested virtualization on this host. Module 'HV' power on

VMware Workstation does not support nested virtualization on this host. Module 'HV' power on failed.

Virtualized AMD-V/RVI is disabled for this ESX virtual machine. You will only be able to run 32-bit nested virtual machines. Failed to start the virtual machine.

I have activated VIRUZALTION IN BIOS

Disable Hyper-V In turn windows features on or off windows 11

OS system : windows 11 Entreprise

CPU AMD Ryzen 7 4700U

Ram :  32 Go

After that I use this command in powershell and reboot system:

bcdedit /set hypervisorlaunchtype off

but the same problem.

Also I changed Change number of CPU cores to 1. 

but the same problem.

disable Device Guard or Credential Guard.

but the same problem.

I don't know what caused this problem, I want to create a study project and install vmware vsphere 7.

When Memory Integrity is turned on, VMware Workstation also uses the Hypervisor API causing nested virtualisation to be unsupported.

Go to Windows Security -> Device Security -> Core Isolation and make sure Memory Integrity is “Off”.

I have exactly the same issue and memory integrity is turned off. But Workstation still refuses to run the nested vsphere 7 VMs, which it does a few weeks ago without any problem,

You have a fellow VMware employee who have the same problem in this thread.

Maybe you could try your internal Slack channel as suggested.
