Best approach to fetch the hostSystem name and names of VMs on the host

Hi There,

My requirement is to fetch the name property of the host and the names of all VMs on that host.

I trying following code, but unable to fetch "vm.name" property. Am i missing something here.

QuerySpec qs = new QuerySpec();

  qs.resourceSpec = new ResourceSpec();

qs.resourceSpec.constraint.targetType = HOST_TYPE;

  // request the name property

  PropertySpec pSpec = new PropertySpec();

  pSpec.propertyNames = new String[]{"name","vm.name"};

  qs.resourceSpec.propertySpecs = new PropertySpec[]{pSpec};

  qs.resultSpec = new ResultSpec();

  qs.resultSpec.maxResultCount = 1;

  // use default ordering

  qs.resultSpec.order = new OrderingCriteria();

  qs.resultSpec.order.orderingProperties = new OrderingPropertySpec[0];

  // get data from DataService

  RequestSpec qsSpec = new RequestSpec();

  qsSpec.querySpec = new QuerySpec[]{qs};

Response response = _dataService.getData(qsSpec);

Thanks
