HP Integrity Virtual Machines 4.3: Release Notes (5900-2265, May 2012)

2 Installation Notes
This chapter contains notes about installing and upgrading Integrity VM and associated software
on the VM Host system.
2.1 Installing Integrity VM
This section describes information about installing the HP Integrity Virtual Machines product and
associated software on the VM Host system.
HP Integrity Virtual Machines B.04.30 is supported on HP Integrity servers or nPartitions running
HP-UX 11i v3 March 2011 Fusion release and HP-UX 11i v3 September 2011 Fusion release.
When you upgrade or reinstall Integrity VM, guests are stopped, but they are not removed. When
the new version of Integrity VM starts, the virtual machines might also start, depending on the
setting of the guest boot attribute.
NOTE: Version 4.3 of Integrity Virtual Machines requires the installation of both the HostAVIOStor
and HostAvioLan bundles.
The VM Host system is not a general-purpose system; it is dedicated to the hosting of virtual
machines. After you install Integrity VM, no operating system or process management reconfiguration
should be performed outside those provided by the Integrity VM interfaces. Specific examples of
actions that are not supported on the VM Host system include:
• Changing priorities or scheduling attributes of processes on the VM Host system.
• Modifying kernel tunables in any way.
Do not install the VM Host software on a VM guest, and do not install the HPVM-Guest software
on the VM Host. Neither configuration is supported.
For complete information about the requirements for installing Integrity VM, see the HP Integrity
Virtual Machines 4.3: Installation, Configuration, and Administration manual.
2.2 Changes and Issues in This Release
The following section describes issues in the V4.3 release.
2.2.1 Upgrading to Integrity VM V4.3
You can upgrade to Integrity VM V4.3 only from Integrity VM V3.5, V4.1, V4.2, and V4.2.5.
Although you can also upgrade to V4.3 from V4.0 or V4.1, these upgrades are not supported,
and these versions are no longer supported.
2.2.2 Compatibility of Insight Dynamics - VSE V6.0 with Integrity VM V4.3
You can use V6.0 of Insight Dynamics - VSE V6.0 with Integrity VM V4.3, but this version of
Insight Dynamics - VSE does not support the new features of Integrity VM V4.3.
2.2.3 Increase base_pagesize Tunable When Using Dynamic Memory Allocation or
Automatic Memory Reallocation (AMR)
Increasing the base_pagesize tunable to 64 provides significant memory savings on the VM
Host system when configuring virtual machines to use Integrity VM's dynamic memory allocation
or automatic Memory Reallocation (AMR). Some software might be impacted and rendered
inoperable by setting the base_pagesize to anything other than the default value. For more
information about setting the base_pagesize tunable, see the white paper Tunable Base Page
Size, available from the HP documentation website.
To set the base_pagesize tunable to the recommended value of 64K, use the following command:
