Memory Section
These bars display the following information about host memory usage:
Table 1-7. Host Memory
Field Description
Consumed Actual consumption of physical memory that has been allocated to the virtual machine.
Overhead Consumption Amount of consumed memory being used for virtualization purposes. Overhead Consumption
