The Integrity VM V4.1 release introduces new the new Online VM Migration feature, which allows you to migrate an active guest and its applications from one VM Host to another without service interruption. New Accelerated Virtual I/O (AVIO) drivers are also supported in this release, which provide accelerated storage and networking products to improve the overall I/O performance for Integrity VM.
