Abstract

As indicated above, aspects of the present invention provide an approach for facilitating nondisruptive virtual machine (VM) maintenance in a networked computing environment. In an embodiment, a request for an update to an active VM is received, and a copy of the active VM is taken to create a snapshot VM. An update is installed on the snapshot VM. While the snapshot VM is being updated, all changes made to the active VM are saved. Once the update is installed on the snapshot VM, the saved changes are applied to the snapshot VM. A switch is made over to the snapshot VM in real time so that the snapshot VM becomes the active VM. The process allows a user to work continuously with the software as a service (SaaS) VM without disruption.
