VMware Workstation does not support nested virtualization on this host. Module 'HV' power on failed Windows 11?


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.
By default it activated VIRTUALIZATION IN BIOS level
Disable Hyper-V In turn windows features on or off windows 11
OS system : windows 11 Enterprise
CPU: AMD Ryzen 7PRO 5850U
Ram : 16GB
VMware workstation 16 pro : 16.2.2
Installed ESXI 6 and ESXI 7 hypervisor
Below is action performed in PowerShell and reboot system:
bcdedit /set hypervisorlaunchtype off and DISM /Online /Disable-Feature: Microsoft-Hyper-V
but the same problem.
Also I changed the number of CPU cores to 1.
but the same problem.
disable Device Guard or Credential Guard.
but the same problem.
After that I fixed it: Windows Security -> Device Security -> Core Isolation and make sure Memory Integrity is “Off”.
Still the problem exists .
I don't know what caused this problem ,however from windows10 it's working fine.
Can anyone suggest to me what goes wrong here ,the problem with Windows 11 or AMD Processor ?178014-amd-vissue.png178039-failedtopoweron.png

    Tried all the above but found that turning off Memory integrity in Core isolation settings resolved it:

    Core Isolation - Memory integrity

    Alternatively, just disable HyperV in Windows features if you are not using HyperV. Reboot and try again.
