  • 1.  Error: Virtualized Intel VT-x/EPT is not supported on this platform.

    I get the error "Virtualized Intel VT-x/EPT is not supported on this platform." when attempting to launch a Window Server 2022 VM with VMWare Workstation Pro 17.6.3.

    Setup:

    Lenovo ThinkPad P1 Gen 7

    Intel Core Ultra 9 185H (Meteor Lake-based, new generation)

    Windows 11 Pro (Host)

    I have turned off and verified none of the Hyper-V services are running. 

    I confirmed there are not any nested VMs.

    These lines are present in the vmx file:

    vhv.enable = "TRUE"     
    hypervisor.cpuid.v0 = "FALSE"
    mce.enable = "TRUE"

    I created a new Ubunto VM and confirmed VT-x is not visible to the Ubuntu guest.

    I exported the VM to an OVF and imported it into VirtualBox and the Windows VM will launch in VirtualBox.   I've tried everything I can find to fix this issue, including everything from ChatGPT.

    Does anyone have know how to resolve this issue or have any additional troubleshooting suggestion?

    Thanks in advance,

    Rob

    Hi,

    Please share the support bundle including the Windows Server 2022 guest OS logs. 

    Thanks.

    Did you check whether VBS (Virtualization Based Security) is off. Here, on this forum, there are discussions describing how to disable the invisible virtualization layer in Windows. Hyper-V services are not enough. You VM's configuration has these two checkboxes checked:

    Unless you want to run Hyper-V inside the VM, you don't need these. Uncheck, then try again. If you need hardware virtualization features within the VM, you'll need to disable VBS.
