Are we this far already? Preview implies functional completeness,
but I'm not sure about all ACPI related parts actually having been
implemented (and see also below). But perhaps things like P and C

Dom0 is perhaps not even experimental at this point, considering
the panic() in dom0_construct_pvh().
