Abstract: Techniques for providing the ability to live migrate a virtual machine from one physical host to another physical host employ shared storage as the transfer medium for the state of the virtual machine. In addition, the ability for a virtualization module to use second-level paging functionality is employed, paging-out the virtual machine memory content from one physical host to the shared storage. The content of the memory file can be restored on another physical host by employing on-demand paging and optionally low-priority background paging from the shared storage to the other physical host.

Abstract: Embodiments are directed to establishing efficient virtual machine reference points and to specifying a virtual machine reference point to query incremental changes. In one scenario, a computer system accesses a stable virtual machine checkpoint that includes portions of underlying data stored in data storage, where the checkpoint is associated with a specific point in time. The computer system then queries the data storage to determine data storage identifiers that reference the point in time associated with the checkpoint and stores the determined data storage identifiers as a virtual machine reference point, where each subsequent change to the data storage results in an update to the data storage identifier, so that virtual machine reference point is usable to identify incremental changes from specific points in time on.

Abstract: Embodiments are directed to backing up a virtual machine cluster and to determining virtual machine node ownership prior to backing up a virtual machine cluster. In one scenario, a computer system determines which virtual machines nodes are part of the virtual machine cluster, determines which shared storage resources are part of the virtual machine cluster and determines which virtual machine nodes own the shared storage resources. The computer system then indicates to the virtual machine node owners that at least one specified application is to be quiesced over the nodes of the virtual machine cluster, such that a consistent, cluster-wide checkpoint can be created. The computer system further creates a cluster-wide checkpoint which includes a checkpoint for each virtual machine in the virtual machine cluster.
