Architecting Tenant Networking with NSX in vCloud Director : IP Address Management and Routing : 5.2 Customer Address Assignment : 5.2.1 Static IP Pool Assignment
   
5.2.1 Static IP Pool Assignment
With Static IP pool assignment, vCloud Director chooses an address from the IP pool assigned to the Org VDC network. On supported guest OS, with VMware Tools™ installed and with “Guest Customization” enabled, the chosen address is then statically configured on the new VM during provisioning. This is the default option within vCloud Director and will result in an error if a VM provision is attempted without an IP pool with at least one spare address assigned to the network.
Figure 20. Static IP Pool Address Assignment
This figure shows a new VM “VM6” being provisioned onto a network called “172.18.2.0_24”. Because the default “Static – IP Pool” method of address selection and assignment is in force, an address will be chosen from a pool assigned to the network (see the following figure).

Unless the enhanced networking workflow is enabled on the Configure Networking page of the vApp provisioning dialogue (see the following figure), Static IP pool is the only option available on the Network Specification tab of the VM configuration shown in Figure 21.
