vSphere and vCloud Director platforms support reconfiguration of existing machines to modify specifications for CPU, memory, storage, or networks. A machine owner can request a reconfiguration when the machine is in either the On or Off state.

Reconfiguration requests are subject to approval based on entitlements, policies, and the actions enabled for the blueprint.

Table 1. vSphere and vCloud Director vApp component machine reconfigure scenarios


Required Entitlements

The machine owner can begin a reconfiguration to run immediately after any required approvals are given.


The machine owner can specify a date and time to run the reconfiguration. Reconfiguration can be rescheduled if the request is not approved until after the scheduled time.


If the reconfiguration fails, the machine owner can retry the operation.

Execute reconfigure

The machine owner can cancel a scheduled reconfiguration, or if a reconfiguration attempt fails, the user can cancel the reconfiguration operation instead of retrying.

Cancel reconfigure

Before proceeding with the reconfiguration, IaaS validates that any additional resources that were requested are available on the machine's current reservation. If the reconfiguration request decreases the amount of resources that the machine uses, these resources are not deallocated and made available to other requests until after the reconfiguration finishes successfully.

If the reconfiguration fails, any additional resources, such as storage, that were allocated in anticipation of the reconfiguration are deallocated and made available to other machine requests.
