HP Integrity Virtual Machines Release Notes Version A.03.50

1 Introduction
Thank you for installing HP Integrity Virtual Machines (also called Integrity VM). This Release
Notes document describes the changes in this version of the Integrity VM product.
The Integrity VM Version 3.5 release introduces new accelerated storage and networking products
to improve the overall I/O performance for Integrity VM. These new Accelerated Virtual I/O
(AVIO) products provide up to a 60% reduction in service demand and as much as a twofold
improvement in throughput over the existing fully-virtualized storage and networking Integrity
VM solutions. Performance depends on the application workload, and in general, is better with
larger message sizes.
HP Integrity Virtual Machines A.03.50 is supported as a host on HP Integrity servers or nPartitions
running HP-UX 11i v2 December 2007 0712 or later. For complete information about the
requirements for installing Integrity VM, see the HP Integrity Virtual Machines Installation,
Configuration, and Administration manual.
NOTE: Integrity VM patches for fixes developed subsequent to the Integrity VM V3.5 release
are available at the HP IT Resource Center (ITRC) website. Go to this website http://
www.itrc.hp.com and download the following patches:

Integrity VM V3.5. In addition, update AVIO with the WEB0803 version.

Host and guests. For the latest version of the AVIO software, check the software depot website,
