Zusammenfassung:Dual Self-Service Terminal (SST) Virtual Machines (VMs) are provided. A VM is selected for processing a transaction on the SST as an active core. The active core is dynamically switched back and forth between a first VM and a second VM on a per-transaction basis. Upon failure, a last-successful image for the failing VM is reloaded for the failing VM when the failing VM is scheduled to be cycled back to the active core.
