HP Integrity Virtual Machines 4.2.5: Release Notes

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.04.20.05 is supported on HP Integrity servers or nPartitions running
HP-UX 11i v3 September 2010 1009). 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 4.2.5 of Integrity Virtual Machines requires the installation of both the
HostAVIOStor and HostAvioLan bundles. Other Integrity Virtual Machines documentation may state
this requirement is optional, but it is not. In addition, to use the AVIO network driver on a Windows
guest, you must install the VMGuestSW bundle.
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.
If the current version of your VM Host AVIO (HostAVIOStor) storage driver is B.11.31.0903 or
later, then before you install Integrity VM V.4.2.5, upgrade the guest AVIO storage driver
(GuestAVIOStor) to B.11.31.1009/B.11.23.0903 or later on both HP-UX 11i v2 and HP-UX 11i
v3 guests.
If you do not upgrade your AVIO guest storage drivers, you might see occasional open failures of
AVIO storage devices.
For complete information about the requirements for installing Integrity VM, see the HP Integrity
Virtual Machines 4.2: Installation, Configuration, and Administration manual.
