 @Description 		SysVzPvzConnectionInit initializes the VM manager para-virtz
					which is used subsequently for communication between guest and
					host; depending on the underlying VM setup, this could either be
					either a hyper-call or cross-VM call

 @Return			PVRSRV_ERROR	PVRSRV_OK on success. Otherwise, a PVRSRV_
									error code

					 to complete the processing for the pvz call or make a VM manager
					 to host pvzbridge call
