VM Objects are the objects which are in Virtual Memory. These are objects which are currently being retrieved and those which were kept in memory for fast access (accelerator mode).
This may also include objects which are stored in the RAM cache (cache_mem) with no disk copy.
This is usually much smaller report than the full objects report. But can still be very, very large.
