HP Integrity Virtual Machines Version 4.2 Release Notes

be backed up regularly on the VM Host system. Do not use the VM Host system as a backup
server. For more information, see the HP-UX 11i v2 Installation and Update Guide.
• Using HP GlancePlus/iX to monitor guests
You can use Glance on the VM Host to monitor guest data, but recorded measurements can
be misleading. Glance receives the CPU accounting information from the guest kernel.
Because the VM Host can take the guest processor away (for example, when a hardware
interrupt occurs), the time spent running other guests is reported for the state that the guest
was in at the time the CPU was taken away. For more information about using Glance, see
glance(1M).
• Using HP Global Workload Manager (gWLM)
If you use gWLM within VSE to manage virtual machines, when you upgrade the VM Host,
make sure the gWLM agent on that host is running gWLM A.02.50 or greater. Also, the
managing VSE Central Management Station (CMS) must be running A.02.50 or greater, as
described in the VSE Management Software Installation and Update Guide. To upgrade the VM
Host, use the following procedure:
1. Remove the gWLM agent using the following command:
# swremove gWLM-Agent
2. Upgrade Integrity VM as described in the HP Integrity Virtual Machines 4.2: Installation,
Configuration, and Administration manual.
3. Upgrade the gWLM agent, as described in the VSE Management Software Installation and
Update Guide.
If you install the current version of Integrity VM without upgrading to gWLM A.02.50 or
later, and then attempt to use gWLM within VSE to manage virtual machines, the following
error is reported:
Error acquiring workload management lock. Look in the the file
/var/opt/gwlm/gwlmagent.log.0 on hostname for more details.
NOTE: You can use gWLM on the VM Host, but only to manage iCAP resources. gWLM
is the workload management solution for managing resource allocation to virtual machines.
• Using the HP Integrity Virtual Machines Manager (VMMgr)
The VMMgr product provides a graphical user interface (GUI) for Integrity VM. It is available
from either of the following management interfaces:
— HP System Management Homepage (SMH).
For more information about using Integrity Virtual Machines Manager under SMH,
see the HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide.
— HP Virtual Server Environment (VSE) Management Software environment in the HP
Systems Insight Manager (SIM) on the Central Management Server (CMS).
For more information about VSE, see the VSE Management Software Quick Start Guide
If you have installed the HP Integrity Virtual Machines Manager software, you must upgrade
it to a version that supports this version of Integrity VM.
To use Integrity Virtual Machines Manager, you must install the VMProvider bundle that
is provided with Integrity VM. If you upgrade Integrity VM, be sure to keep the VMProvider
up-to-date also. If the VMProvider version does not match the Integrity VM version, the
Integrity Virtual Machines Manager will not work properly.
For Windows guests, install the WMI Utilization Provider (UtilProvider) software provided
with the HP Integrity Support Pack for Windows. Follow the instructions for installing
