Well, a simple justification:

Tivoli's statement of support for TSM, says they do not support the TSM
server on any machine that has tape drivers.  That means either physical
tape, or VTL's (which are emulating tape).

http://www-01.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=server+support+vmware&uid=swg21239546&loc=en_US&cs=utf-8&lang=en

An all-disk TSM server config is supported as a VM.
