For Reboot and Shutdown, th RequestStateChange method returns immediately with return code 0 (successful) even though the state change is still not completed.
According to the DMTF specification DSP1052 (Computer System Profile) the RequestStateChange() method should return 0x1000 and a corresponding job reference in the return parameters which can be polled for completion.

Sharad has just found another issue here, for shutdown the event is VIR_DOMAIN_EVENT_ID_LIFECYCLE, and not VIR_DOMAIN_EVENT_ID_REBOOT. -- Eduardo de Barros Lima Software Engineer, Open Virtualization Linux Technology Center - IBM/Brazil eblima@br.ibm.com
