IBM has an enormous library of freely available documentation. The underlying z/VM environment is approachable described in:
[Getting Started with z/VM for Linux](http://publibz.boulder.ibm.com/epubs/pdf/hcsx0c31.pdf)
Which is IBM document SC24-6194-06 (August 2017)
In one of the discussion and community (and professional but free) support mailing lists, that work was described by an IBM professional on one the freely available mailing lists thus:
One of the simplest is the Getting Started with z/VM for Linux manual that is part of the z/VM library. It was intended as a basic fishing lesson, as opposed to just handing you fishing [tackle]
In IBM documentation identification, the last two digits indicate the revision level of the document, here: -06 and was released, not unexpectedly, in August 2017
There is something of acquiring a new skill in reading IBM documentation. At one time, IBM was said to be the third largest publisher of originally authored document in the US, behind the US Department of Defense, and the Boy Scouts of America. Not surprising, each of the three is in the business of training people from wholly ignorant of a field, to full competence. Reading the (fine manual) documentation is to learn from professionally designed, and maintained training materials. That said, as the documentation cannot assay your particular level of competence in an area, it has to have parts that you 'already know', and may safely skip over
As intimated, there are several mailing lists to which one may freely subscribe, read, watch discussion between professionals, and so to learn.
