Virtual machines
OMPC monitors the devices, manages the power consumption, and aggregates the observations in the form of a report. However, only
physical devices such as server, chassis, UPS, or PDU are monitored. Currently, the power consumption of virtual machines is not
monitored.
Starting OMPC 4.0, you can discover hypervisors, enumerate virtual machines on the hypervisor, manage power tasks, evaluate, and
generate power consumption reports.
The metrics from the report enable data center administrators to:
Compute power utilization of the virtual machines.
Identify a potential problem.
Prioritize the workload based on actual power consumption.
Provide usage chargeback.
After you discover the devices, the hypervisors associated with that particular device are displayed in the Virtual Machines feature tab.
Only the hypervisors associated with a physical device that was discovered, is selected for processing. If you remove a physical server from
OMPC, all the associated hypervisors and virtual machines are deleted.
You can move a virtual machine from one physical host to another. The virtual machine is allocated a unique identier, through which it can
be identied in the physical host after the migration. In this way, all the information related to the virtual machine is preserved even after
the virtual machine is migrated to a dierent physical host.
NOTE
: You cannot delete a discovered virtual machine. However, you can delete the device with which the virtual machine has
been associated, that eventually deletes the corresponding hypervisors and virtual machine.

Filtering virtual machines
The lter feature in the Virtual Machines tab helps you to view the virtual machines that share a certain attribute. For example, you can
lter and view the virtual machines based on the IP range or the status.
1 In the left pane, click Virtual Machines.
The Virtual machines tab is displayed by default.
2 From the task menu, click Filter.
