Tenant administrators can reclaim virtual machines in their tenant to help control resource use.

A tenant administrator can use filters such as low CPU use, low memory use, low hard disk use, and low network use to identify underused machines that might be candidates for reclamation. After selecting the candidate machines, the administrator can send a reclamation request to the owners of the machines.

The machine owner has a fixed period of time to respond to the request. If the machine is still in use, the owner can stop the reclamation process and continue using the machine. If the machine is no longer needed, the owner can release the machine for reclamation, in which case the machine is destroyed immediately, depending on the reclamation workflow, and its resources are freed up for other machines to use. If the owner does not respond in a timely manner, a lease determined by the administrator is imposed. If the owner continues to take no action, the machine is powered off on the new expiration date, the machine is reclaimed, and the resources are freed.
