    abstract     = "Most people believe that the mainframe platform currently suffers a slow but a certain death. This is however a common misconception: The mainframe is very much alive and going strong.

This thesis recognizes the mainframe platform’s superior qualities, and deals with one of the platform’s new driving forces: Server consolidation based on the z/{VM} operating system and Linux.

Some effort is first made to provide a basic understanding of the {IBM} mainframe architecture in order to establish common ground. A concise, yet theoretically and practically balanced, description of z/{VM} based virtualization follows. This provides amongst other things insight into how resources (processors resources in particular) can be shared.

The report also introduces some of the most important issues, which set apart mainframe Linux from Linux on other platforms. Performance tests have been carried out, and through these an insight into the systems behaviour can be gained.

The thesis also includes initial considerations on monitoring software for the virtual server environment on the mainframe."
