Remember, TSM (a.k.a. WDSF, ADSM) was originally _invented_ as a
virtualized application, under the system now known as z/VM, and was
supporetd there until V3.7. It should still have the fundamental design
to deal with running in a virtual machine. It does need resources such
as tapes to be dedicated to it, and it may take some work to get those
resources connected right. But a virtual machine should actually be
considered TSM's historic native environment.
