Fail to open VM

Hi,

I am very new to VIX and I was trying some of the sample on my machine.

However, I am always seeing the hostHandle return as 0 after the VixHost_connect/VixJob_Wait call . As the result, the next line when it calls VixVM_Open, it returned the invalid handle error.  Can you help?

Below is the snippet from the powerOn.c.

#define USE_WORKSTATION

#ifdef USE_WORKSTATION

#define  CONNTYPE    VIX_SERVICEPROVIDER_VMWARE_WORKSTATION

#define  HOSTNAME ""
#define  HOSTPORT 0
#define  USERNAME ""
#define  PASSWORD ""

......................................................................................................................

jobHandle = VixHost_Connect(VIX_API_VERSION,
                                CONNTYPE,
                                HOSTNAME, // *hostName,
                                HOSTPORT, // hostPort,
                                USERNAME, // *userName,
                                PASSWORD, // *password,
                                0, // options,
                                VIX_INVALID_HANDLE, // propertyListHandle,
                                NULL, // *callbackProc,
                                NULL); // *clientData);
    err = VixJob_Wait(jobHandle,
                      VIX_PROPERTY_JOB_RESULT_HANDLE,
                      &hostHandle,
                      VIX_PROPERTY_NONE);
    if (VIX_FAILED(err)) {
        goto abort;
    }

    Vix_ReleaseHandle(jobHandle);
    jobHandle = VixVM_Open(hostHandle,
                           vmxPath,
                           NULL, // VixEventProc *callbackProc,
                           NULL); // void *clientData);
    err = VixJob_Wait(jobHandle,
                      VIX_PROPERTY_JOB_RESULT_HANDLE,
                      &vmHandle,
                      VIX_PROPERTY_NONE);
    if (VIX_FAILED(err)) {
        goto abort;
