Zusammenfassung:The invention relates to a method and a system for failover detection and treatment in checkpoint systems. A method for treatment of a hypervisor call sequence, in a system having a plurality of hosts, includes assigning a host ID to a plurality of hosts in the system; identifying a first host ID for a host from which a first hypervisor call of a hypervisor call sequence originates; identifying a second host ID for a host from which a second hypervisor call of the hypervisor call sequence originates, wherein the second hypervisor call is a call subsequent to the first hypervisor call; and determining whether the second host ID is equal to the first host ID.
