Abstract
The present invention provides a system and method for fast restart of a guest operating system executing on a virtual machine operating system in a virtual machine environment. During initialization, the guest operating system saves a set of checkpoint information to persistent storage. Upon detection of an error condition during operation, the guest operating system begins a re-initialization procedure in accordance with an illustrative embodiment of the present invention. During the re-initialization procedure, the guest operating system retrieves the checkpoint information and configures itself using the retrieved information. By utilizing the retrieved information, the guest operating system avoids the need to perform lengthy configuration discovery routines, thereby shortening the re-initialization time substantially.
