The one you've picked looks to be a "fail never pass" one, so is perhaps
not ideal. I've looked at a couple other ones, and in particular when the
guests are supposedly 64-bit I notice two things
- they look to be busy looping on vCPU 0,
- the VMCS/VMCB dumps suggest they've never left early boot (i.e.
  are still in 32-bit mode with paging still disabled), and may well still
  be sitting inside the boot loader.
I'm not at all certain though if this helps in any way.
