HP Integrity VM Manager

AVIO Patches/Drivers Information in Help Is Not Up to Date

The Features and Capabilities help page includes information about AVIO patches and drivers that is out of date; this information will be updated with the next release of VM Manager. The HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide has the correct information in the preface. The up to date information is as follows:

Support for AVIO virtual network devices for Windows and Linux guests requires that compatible Windows and Linux drivers be installed on the guest and additional patches be installed on the Integrity VM versions 3.5 or 4.0. The Windows guest AVIO drivers are included in the VMGuestSW bundle available from the software depot at the following website:

http://software.hp.com

Search for “VMGuestSW” and select the link for Integrity Virtual Machines (HP-UX 11i v3 VM Host).

	NOTE: The HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide and HP Integrity Virtual Machines Manager Version 4.0 Release Notes released for the HP Insight Software DVDs have incorrect information about the location of Windows guest AVIO drivers. This error has since been corrected for the web releases of these two documents. The correct location is the software depot site indicated in the preceding paragraph.

At the time of publication of this document, the Linux guest AVIO drivers are not yet available.

The Integrity VM version 3.5 patches are PHSS_38297 and PHSS_38298. The Integrity VM version 4.0 patches (for HP-UX 11i v3) are PHSS_38566, PHSS_38567, PHSS_38611, PHSS_38631. Integrity VM version 4.0 supports Windows and Linux guest AVIO networking with these Integrity VM version 4.0 patches.

Information About Utilization Meter Labels Is Incorrect in Help

The following statements in the indicated help pages are incorrect or incomplete and will be corrected with the next version of VM Manager, as noted:

Documentation on Discrepancies Between Capacity Advisor CPU Data and VM Manager CPU Utilization Meter Data

The following appears in a note in the “Collecting and Viewing Utilization Data” section of the HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide but was not included in the online help:

Data reported by certain VM Manager CPU utilization meters might vary from the data collected by Capacity Advisor as displayed in the Profile Viewer and historical utilization reports. The data from VM Manager meters is reliable for most purposes. For capacity planning, refer to the data collected by the Capacity Advisor Profile Viewer and historical utilization reports. For more information about how Capacity Advisor data might vary from VM Manager data, see the section entitled “Data Handling for Virtual Machines” in Chapter 3 of the HP Capacity Advisor Version 4.1 User's Guide.

	NOTE: Another source of discrepancy is the difference in the way Capacity Advisor and VM Manager present CPU data. Capacity Advisor Profile Viewer and historical utilization reports present CPU data in absolute terms (specifying the number of physical cores used) while VM Manager presents CPU data in terms of percentages (specifying the percentage of available CPU resources being used). For example, the VM Manager “VM Host CPU Utilization” meter displayed on the VM Host Virtual Machines and VM Properties General tabs displays the percentage of the total VM Host physical CPU capacity used by the virtual machine in question. Capacity Advisor tabulates similar data but presents it in different terms. For example, on a VM Host that has 16 physical cores, if a VM has 4 vCPUs each currently using 50% of a physical core, CapAd would say the VM is consuming 2 cores. The VM Manager “VM Host CPU utilization” meter would say the VM is consuming 12.5% of the VM Host's CPU capacity.

VM Manager Software Versions Specified in Publishing History Table of Getting Started Guide

When the HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide was released for the HP Insight Software DVDs, the exact software version number of VM Manager was not known; therefore, it was not specified in the Publishing History table in the preface. The correct software version is A.04.00.00.70. In addition, the software version for the October 2008 release of VM Manager (for standalone use with HP SMH only) was incorrectly specified in that table as A.04.00.01. It should have been specified as A.04.00.00.01.
