Abstract:
The invention introduces a method for session failover in OS (Operating System) level, which contains at least the following steps. A VM (Virtual Machine) OS is selected to perform a failover when a server OS is determined to have failed. A memory and a local storage device of the VM OS are mapped to the physical memory space and physical storage space of a distributed share-memory-and-cloud-storage, which were allocated for the failed server OS via a hypervisor corresponding to the VM OS. The OS state of the failed server OS is obtained from a distributed cache system via the hypervisor.
