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:

Even 32 times with 16 lanes on POWER9 :-)[ Edited by Andreas_Wolf 14.03.2019 - 12:52 ]
