HP Integrity Virtual Machines 4.2.5: Release Notes

Serviceguard, as documented in the HP Integrity Virtual Machines Installation, Configuration, and
Administration manual.
• Using backup solutions for VM Host and guest backups
Backup solutions such as HP Data Protector or Veritas NetBackup can be used on both the
VM Host system and the guest systems. Consult the support matrix of such products for supported
versions. Install the backup (client) agents on the VM Host and the guests. HP highly
recommends that the /var and /opt directories, in addition to the standard locations, 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 Insight Dynamics — 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 Insight Dynamics — VSE Central Management Station (CMS)
must be running A.02.50 or greater, as described in the HP Insight Dynamics —VSE 6.0:
Integrity CMS Installation and Configuration 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 HP Insight Dynamics — VSE 6.0: Integrity
CMS Installation and Configuration 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 Insight Dynamics — 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 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 Insight Dynamics — VSE Management Software environment in the HP Systems Insight
Manager (SIM) on the Central Management Server (CMS).
