    Existing mac99 virtualization is fully sufficient and can run AltiVec binaries. X5000 virtualization, beside not yet existing, couldn't. What advantages would it have for running MorphOS?

    Yet, a host OS that runs directly on PowerNV (i.e non-virtualized) with access to OPAL is not running in a 'box', at least according to my understanding of the term. Otherwise, it'd be hard to distinguish such host OS from virtualized guest environments.

    Edit: clarifying quote:
    "there is no hypervisor under Linux when we're using the powernv platform, Linux *is* the hypervisor."

    ...as could OS4 ;-)

    Even 32 times with 16 lanes on POWER9 :-)
