Discontinued functions
The following functions are discontinued in this release:
Virtual machine operations on the backup-archive client
Virtual machine operations are available only if you are using the client as a 
data mover for the IBM Spectrum Protect for Virtual Environments products (Data 
Protection for VMware or Data Protection for Microsoft Hyper-V).
You can no longer run virtual machine operations without installing IBM 
Spectrum Protect for Virtual Environments.
What does "Virtual machine operations" mean?    Do TSM's basic backup/archive 
functions stop if the 8.1 client is running as a VM guest and Spectrum Protect 
for VE is not installed???
