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.
