Interfaces in virtualize OPM enterprise model

Interfaces in virtualize OPM enterprise model

I have build an OPM enterprise system on VMWare (all devices in this model are  virtualized by GNS3 and VMWare ).
In OPM (both Central and Probe), when I select tab Network -> All Interfaces, I cant see any interface in my model (It shown "No record to views").  Is this normal? 
If I build an OPM model in real system (not virtualize), can it monitor all my system's interfaces?
