Windows 10 2004 VMLAUNCH failed

[Hulkstance]

I tested it on Windows 10 2004 release and it BSODd with:

EXIT_REASON_INVALID_GUEST_STATE
Arguments:
Arg1: 0000000000000001
Arg2: 0000000000000021
Arg3: 0000000000000000
Arg4: 0000000000000000

VOID VmExitStartFailed( IN PGUEST_STATE GuestState )
{
    DPRINT(
        "HyperBone: CPU %d: %s: Failed to enter VM, reason %d, code %d\n",
        CPU_IDX, __FUNCTION__, 
        GuestState->ExitReason, GuestState->ExitQualification 
        );

    KeBugCheckEx( HYPERVISOR_ERROR, BUG_CHECK_INVALID_VM, GuestState->ExitReason, GuestState->ExitQualification, 0 );
}

Maybe you can try to modify these places to support win10, my system version is win10 1909

add

change

- __vmx_vmwrite( GUEST_CR3, *regPtr );
+ __vmx_vmwrite( GUEST_CR3, ( *regPtr & ~(1ULL << 63) ) );
