Windows 2012 R2 HyperV Licensing -- antiVirus/etc on HOST ?

Windows licensing states the below
 1. purchase one Windows 2012 R2 STANDARD license
 2. ONLY run MANAGEMENT software on the HOST
 3. run up to two HyperVs with the one above license

I assume I need another Windows 2012 R2 STANDARD
license to install antiVirus or backup/recovery
software on the host ?

I also asked my Microsoft rep, but want
to get everyone's stance on the above
to see what people are doing.

You can run Hyper-V supporting services on the hardware install - that includes backup and antivirus.  You cannot run other non-Hyper-V supporting roles on the server - such as adding the file server role, etc.

I agree with Lee about who the ultimate authority is on licensing. Microsoft is a real pain to deal with on licensing, while you can get a general consensus on here about what others have done, the end result will be what your microsoft rep tells you.

Backup and recovery via the host is a part of the ongoing virtualization stack services. No hit there.

We suggest to not run A/V clients on the host as a rule. The endpoints are where that belongs and where infections happen.
