You can specify only one Amazon VPC when you create a private hosted zone. If you are associating a VPC with a hosted zone with this request, the paramaters VPCId and VPCRegion are also required.

To associate additional Amazon VPCs with the hosted zone, use AssociateVPCWithHostedZone after you create a hosted zone.
