Adopt Resource Pools With a VDC

When adding a VDC to an organization, a system administrator can specify one or more resource pools that are available in the supporting Provider VDC. When the VDC is created, the specified resource pools are said to have been adopted by the VDC. Any vCenter VMs that exist in an adopted resource pool become available as discovered vApps in the new VDC.

When you create an organization VDC without specifying a resource pool, the system creates the VDC using the default resource pool of the specified Provider VDC. Before creating an organization VDC, you can query a Provider VDC to get a list of all resource pools that are candidates for adoption by the new VDC. If any resource pools contain VMs created in vCenter that your organization would like to access in a VDC, specify those pools when you create the VDC. vCenter VMs in the specified pools appear in the new VDC as discovered vApps and are candidates for adoption.

Prerequisites

This operation is restricted to system administrators.

Procedure

Choose a provider VDC to supply resources for the new organization VDC
1. Retrieve the XML representation of the VCloud object and examine the ProviderVdcReferences element it contains.
  The following request retrieves the representation of the VCloud object:
```
GET https://vcloud.example.com/api/admin
```
  The VCloud element contains a ProviderVdcReferences element. Each provider VDC in the system is represented in that element by a ProviderVdcReference element, as shown here:
```
<ProviderVdcReference
   type="application/vnd.vmware.admin.providervdc+xml"
   name="Main Provider"
   href="https://vcloud.example.com/api/admin/providervdc/2"/>
```
2. (Optional) List the organization VDCs that each ProviderVdc supports.
  The following request retrieves the list of organization VDCs that .../providervdc/2 supports:
```
GET https://vcloud.example.com/api/admin/providervdc/2/vdcReferences
```
  Taking this optional step can help you allocate ProviderVdc resources equitably across the organization VDCs in a cloud.

Retrieve the XML representation of the provider VDC you have chosen to back the new organization VDC.

The VMWProvderVDC response body includes a Link of the following form:

<Link
   rel="down" href="https://vcloud.example.com/api/admin/extension/providervdc/2/discoverResourcePools" 
   type="application/vnd.vmware.admin.vmwDiscoveredResourcePools+xml"/>"

Retrieve the list of resource pools that are candidates for adoption by a VDC backed by the selected Provider VDC.

Use the Link shown in Step 3 to make a request like this one:

GET https://vcloud.example.com/api/admin/extension/providervdc/2/discoverResourcePools
...

         <vmext:VimObjectType>RESOURCE_POOL</vmext:VimObjectType>
      </vmext:ResourcePoolVimObjectRef>
   </vmext:VMWDiscoveredResourcePool>
</vmext:VMWDiscoveredResourcePools>

Create a CreateVdcParams request body.
See the request portion of Add a VDC With an Adopted Resource Pool to an Organization.
POST the CreateVdcParams request body to the organization's add link for vdcs.
See the request portion of Add a VDC With an Adopted Resource Pool to an Organization.

Example: Add a VDC With an Adopted Resource Pool to an Organization

This example modifies the request shown in Create an Organization VDC with Pay As You Go Reservation Allocation Model to add a ResourcePoolRefs element that specifies the resource pool identified in Step 3.
