Abstract
A resource reservoir is provided. The resource reservoir is a pool of resources that are allocated to and shared between a plurality of reserve virtual machines. A reserve virtual machine of the plurality of reserve virtual machines corresponds to a primary virtual machine from a plurality of primary virtual machines. Each reserve virtual machine of the plurality of reserve virtual machines fulfills a resource requirement from the resource reservoir. The sum of the resources requirements of the plurality of reserve virtual machines is greater than a sum of total resources within the resource reservoir. In response to determining a decrease in performance of the primary virtual machine, at least a portion of workload of the primary virtual machine is applied to the corresponding reserve virtual machine. The resources used by the reserve virtual are indicated as unavailable to the remaining reserve virtual machines from the resource reservoir.
