VIRTUAL MACHINE MIGRATION TECHNIQUES

Techniques for migrating a virtual machine from a source computer system to a target computer system are disclosed. In an exemplary embodiment, a group of pages can be mapped writable in response to determining that the guest operating system attempted to change a specific page. In the same, or other embodiments, pages can be compressed prior to sending such that throughput of a communication channel is maximized. In the same, or other embodiments, storage IO jobs can be canceled on a source computer system and reissued by a target computer system.
