Breakdown between apps and OS, can be code running in priviledged processor
mode vs non as well. Helps to know if a driver is going nuts or some web 
service.

Yes All of these items presented are about either the Virtual Machine or code 
running in the 
virtual machine.

Yes, they want that.

Yes, that's one way. There could be others. More typically there will be 
SNMP agent running in the Guest OS that is polled separately and/or have an
entry in ENTITY-MIB with hypervisor is another way.

Makes sense to me. In fact I'd prefer if there was prose in the MIB to
explain all how and where we recommend they look for these items.
