If you are using vCloud Automation Center workflows to execute vCenter Orchestrator workflows that have input or output parameters of type VC:VirtualMachine, verify that you have the vCenter Orchestrator workflows for converting virtual machine types between vCenter Orchestrator and IaaS.

The required workflows are included by default in vCenter Orchestrator 5.5 as part of the vCenter plugin.

If you are using vCenter Orchestrator 5.1, install the vCloud Automation Center integration package for vCenter Orchestrator. Download the package com.vmware.library.vcenter.vcac-integration.package from thevCenter Orchestrator community site at http://communities.vmware.com/community/vmtn/server/vcenter/orchestrator. Import the package on each vCenter Orchestrator server that you set up as an endpoint in IaaS.

For information about importing packages to vCenter Orchestrator, refer to the vCenter Orchestrator documentation.
