## Managed Object Description

The Datacenter managed object provides the interface to the common container object for hosts, virtual machines, networks, and datastores. These entities must be under a distinct datacenter in the inventory, and datacenters may not be nested under other datacenters.

Every Datacenter has the following set of dedicated folders. These folders are empty until you create entities for the Datacenter.

- A folder for VirtualMachine, template, and VirtualApp objects.
- A folder for a ComputeResource hierarchy.
- A folder for Network, DistributedVirtualSwitch, and DistributedVirtualPortgroup objects.
- A folder for Datastore objects.

For a visual representation of the organization of objects in a vCenter hierarchy, see the description of the ServiceInstance object.

network* | ManagedObjectReference[] to a Network[] | A collection of references to the network objects available in this datacenter.
networkFolder P | ManagedObjectReference to a Folder | A reference to the folder hierarchy that contains the network entities for this datacenter. The folder can include Network, DistributedVirtualSwitch, and DistributedVirtualPortgroup objects. This folder is guaranteed to exist. Since vSphere API 4.0

# PowerOnMultiVM_Task(powerOnVm)

Powers on multiple virtual machines in a data center. If the virtual machines are suspended, this method resumes execution from the suspend point. The virtual machines can belong to different clusters in the data center.

If any virtual machine in the list is manually managed by DRS, or DRS has to migrate any manually managed virtual machine or power on any manually managed host in order to power on these virtual machines, a DRS recommendation will be generated, and the users need to manually apply the recommendation for actually powering on these virtual machines. Otherwise, all the virtual machine will be automatically powered on. The virtual machines on stand alone hosts or DRS disabled will be powered-on on the current host. The DRS automatically managed virtual machines will be powered-on on the recommended hosts.

When powering on a virtual machine in a cluster, the system might do an implicit relocation of the virtual machine to another host.

Parameters

Name | Type | Description

vm P | ManagedObjectReference[] to a VirtualMachine[] | The virtual machines to power on.
option* | OptionValue[] | An array of OptionValue options for this power-on session. The names and values of the options are defined in ClusterPowerOnVmOption. Since vSphere API 4.1

*Need not be set P Required privilege: VirtualMachine.Interact.PowerOn

Return Value

Type | Description
--- | ---

Faults

Type | Description
--- | ---
InvalidArgument | Thrown for unknown option keys or bad values.

# QueryConnectionInfo(queryConnectionInfo)

This method provides a way of getting basic information about a host without adding it to a datacenter. Connection wizards typically use this method to show information about a host so a user can confirm a set of changes before applying them.

Required Privileges
  System.View

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the Datacenter used to make the method call.
hostname | xsd:string | The target of the query.
port | xsd:int | The port number of the target host. For ESX 2.x this is the authd port (902 by default). For ESX 3.x and above and for VMware Server hosts this is the https port (443 by default). You can specify -1 to have the vCenter Server try the default ports.
username | xsd:string | The name of the user.
password | xsd:string | The password of the user.
sslThumbprint* | xsd:string | The expected SSL thumbprint of the host's certificate Since VI API 2.5

*Need not be set

Return Value

Type | Description
--- | ---
HostConnectInfo |

Faults

Type | Description
--- | ---
AlreadyConnected | Thrown if the host is already being managed by this server.
HostConnectFault | Thrown if an error occurred when querying about a host. Typically, a more specific subclass, such as AlreadyBeingManaged, is thrown.
InvalidLogin | Thrown if unable to authenticate with the host.
NoHost | Thrown if unable to contact the host.
NotSupported | Thrown if called directly on a host.
NotSupportedHost | Thrown if the software version on the host is not supported.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
SSLDisabledFault | Thrown if the host has ssl access disabled
SSLVerifyFault | Thrown if the host certificate could not be authenticated

# QueryConnectionInfoViaSpec(queryConnectionInfoViaSpec)

This method provides a way of getting basic information about a host without adding it to a datacenter. This method is similar to QueryConnectionInfo, but it takes a HostConnectSpec as argument, instead of list of parameters.

Since
  vSphere API 6.0

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the Datacenter used to make the method call.
spec | HostConnectSpec | The connection spec for the host to be queried. It must contain values for all parameters required by QueryConnectionInfo See QueryConnectionInfo or a list of thrown expections.

GatewayNotFound | Thrown if the host is managed via host gateway and no available gateway server is found for the given parameters
GatewayNotReachable | Thrown if the host is managed via host gateway and vCenter Server cannot establish a network connection to the gateway server, or verify the gateway server's identity
GatewayOperationRefused | Thrown if the gateway server cannot accept more host connections
GatewayToHostAuthFault | Thrown if the host is managed via host gateway and the gateway server needs additional information to authenticate before the host
