Virtualization and CPU Wait Times in a Linux Guest Environment

Overview The virtualization environment presents the opportunity to better manage and more efficiently utilize computing resources. The resource sharing aspects of virtualization does, however, create some new challenges from an application implementation and system support perspective. This paper addresses one of those challenges; how does one monitor and manage the behavior of the virtual environment when contention for its physical resources causes significantly long delays in processing to occur? A specific example, with data, is provided where one CPU is shared among three Linux Guests and processing demand among these guests result in significantly long virtual CPU wait times.
