Description

I have the following overrides for my WinXP guest:

      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000002/eax" value="0x65746e49"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000002/ebx" value="0x2952286c"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000002/ecx" value="0x726f4320"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000002/edx" value="0x4d542865"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000003/eax" value="0x43203229"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000003/ebx" value="0x20205550"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000003/ecx" value="0x20202020"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000003/edx" value="0x20202020"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000004/eax" value="0x30303636"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000004/ebx" value="0x20402020"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000004/ecx" value="0x30342e32"/>
      <ExtraDataItem name="VBoxInternal/CPUM/CPUID/80000004/edx" value="0x007a4847"/>

unfortunately 80000003 overrides don't work both with or without Intel-VT enabled.

I'm attaching two screenshots as a proof.

Works here. Are you sure that VT-x is enabled? Could you attach a VBox.log file of a VM session when VT-x is enabled?
