    Help with VirtualBox and WIndows 10 build 1803


    Hello!

    Before build 1803 my VM was working fine! Now I cannot create any 64 bit machine, my VM is not working complaining the Hyper-V etc... I have a second drive with boot, installed VirtualBox there and the 64bit is available, so the issue remains with that new build.

    My Windows is Home Edition, I don't have Hyper-V option to install/uninstall.

    The thing simply stopped to work

    You have to provide a clearer explanation of the hyper-v error message.

    Actually the error is not showing option for allow creating 64bit OS.

    Now with my previous Linux VM I have that message:
    "Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT)."

    And the other shows:
    "VT-x is not available (VERR_VMX_NO_VMX)."

    EDIT: Also, I cannot increase the number of CPU, its grayed on I can't change.
    My other boot, same computer, can handle with that, but of course I need to start these VM on this boot session.

    If you're on Home, I'm not sure if this will be of help, but I had the same problem and fixed it by setting a local policy to disable the Virtualization Base Security in Win 10:

    Hi.

    For Windows 10 Home and newest versions, need to disable in registry.

    Code:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity
    Enabled = 0
