This report summarizes the results obtained with measurements of I/O performance in Xen paravirtualized machines. Focus was put on the performance differences between storage virtualized on a file system as opposed to directly based on a native partition. The experiments are structured in a repeatable and controlled way. Some important notions are also discussed about hard disks geometry and measurement units.

Abstract
This report summarizes the results obtained with measurements of I/O performance in Xen paravirtualized machines. Focus was put on the performance differences between storage virtualized on a file system as opposed to directly based on a native partition. The experiments are structured in a repeatable and controlled way. Some important notions are also discussed about hard disks geometry and measurement units.
