Introduction
As is the case with any relatively new technology, there are a lot of questions surrounding basic use
of that technology, tips on how to get the most out of that technology, and common pitfalls for the new
user. This white paper provides an assortment of guidelines for deploying one or more virtual
machines (VMs) with the Integrity Virtual Machines product. The scope of this white paper is limited
to the Integrity Virtual Machines product, also referred to simply as Integrity VM. Several other HP
products are discussed and references for more information on those products are provided in the
appropriately-named ‘For more information’ section of this paper.
Basics – Read This First
In the event you are about to do your first deployment or are troubleshooting problems with an
existing deployment, take a moment to make sure you have a supported configuration. Common
problems are often addressed by checking a few basic items, including:
• The physical Integrity Server with the Integrity Virtual Machines product installed on it is commonly
referred to as the Integrity VM Host or simply the VM Host. The VM Host must be running a version
of HP-UX supported by Integrity VM. Version 1.2 and 2.0 of Integrity VM are supported on HP-UX
11iv2 0505, 0512, 0603, and 0606. Version 2.0 is also supported on 11iv2 0609.
• The Integrity VM Host may require a few patches, depending on the version of HP-UX it is running.
These will be listed in the Integrity VM release notes along with instructions for obtaining and
installing them.
• Make sure the OS running on the virtual machine, i.e., the guest, has the correct patches and
tunable settings for the workload running there. Do not modify the tunable settings on the VM Host
to accommodate a workload executing in a virtual machine. Do not modify the VM Host’s tunables
as they will be modified during installation of Integrity VM to provide optimal performance and
functionality for hosting virtual machines.
• Read the Integrity VM release notes.
