This document provides an overview of PowerKVM, an open source virtualization option for Linux systems on IBM Power servers. It discusses PowerKVM and PowerVM virtualization, highlighting that PowerKVM supports only Linux guests while PowerVM supports AIX, IBM i and Linux. Management options for PowerKVM include open source tools while PowerVM supports proprietary tools and PowerVC for both virtualization platforms. The document also presents performance benchmarks showing Power8 significantly outperforming Intel Xeon processors.

Key Facts About Linux
 Linux is the world’s fastest growing OS (33.8% revenue share in 2009)
 Over 90% of world’s fastest supercomputers, including top 10 in TOP500 list, run on Linux
 8 of the world’s top 10 websites including Google, YouTube, Yahoo, Facebook, and Twitter run on Linux
 80% of all Stock Exchanges in the world rely on Linux
 95% of the servers used by Hollywood studios for animation films run on Linux
 US Department of Defense is the "single biggest install base for Red Hat Linux" in the world
 Linux has strong following in smartphones & other electronic devices.

Feature Benefits
Simultaneous Multi-Threading 8 Improve system performance by increasing the throughput of
workloads with large or frequently changing working sets, such as
database servers and Web servers by
 Ability to invoke up to 8 concurrent threads per core
 Ability to schedule threads across core
 Ability to designate/change primary thread
Java Code Optimization w/HW
Assist
 Taking already strong Java performance to the next level, included
as part of Java Runtime, hardware helpers for Java IT code
optimization
Transactional memory  Reducing customer cost by Improving performance of legacy
software with large sequential components
Efficient power management  Lower power usage at idle
 Optimized workload power management
 Improved performance per watt at moderate utilizations
PCI Gen3  Significant increase in bandwidth and reduction in latency
 Required for Analytics, Big Data.
 Coupled with memory bandwidth drives higher compute than x86
Coherent accelerator processor
interface*
 Virtual Addressing & Data Caching
 Easier, more natural programming model
 Enables applications not possible on I/O
