Virtual Machine State Diagram
The following diagram illustrates the operational states and state transitions of a virtual machine session.
Virtual Server will generate one or more state changed events through the IVMVirtualServerEvents::OnVMStateChange and IVMVirtualMachineEvents::OnStateChange methods every time a virtual machine session changes states. State changes of a virtual machine session are controlled by invoking methods of the IVMVirtualMachine interface.
The following table lists the state changed events generated by Virtual Server for virtual machine sessions.
| IVMVirtualMachine method | State change events generated |
|---|---|
| StartUp (no previous state saved) | vmVMState_TurningOn vmVMState_Running |
| Save | vmVMState_Saving vmVMState_TurningOff vmVMState_DeleteMachine vmVMState_TurnedOff |
| Startup (restoring from a saved state) | vmVMState_TurningOn vmVMState_Restoring vmVMState_Running |
| Reset | vmVMState_TurningOff vmVMState_DeleteMachine vmVMState_TurningOn vmVMState_Running |
| Pause | vmVMState_Paused |
| Resume | vmVMState_Running |
| TurnOff | vmVMState_TurningOff vmVMState_DeleteMachine vmVMState_TurnedOff |
