HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

• System performance monitoring tools (GlancePlus, Measureware, OpenView Operations
Agent)
• Utility pricing tools (Instant Capacity, Pay per use)
• Hardware management tools (nPartition Manager, storage and network management tools)
• Multipath storage solutions
• HP Serviceguard (which can be run on HP-UX guests as well).
Regardless of whether guests are running, do not run other applications on the VM Host system.
Example of applications that should not be run on the host are: Oracle, Workload Manager
(WLM), HP SIM, and so forth. Integrity VM installation modifies kernel parameters, making the
system unsuitable for running applications.
A guest running on a virtual machine runs the way it does on a physical system. By allocating
virtual resources, you provide the guest operating system and applications with access to memory,
CPUs, network devices, and storage devices as if they were part of a dedicated system.
Typical software you can run on a guest includes the following:
• HP-UX 11i V2 or V3 Virtual Server Operating Environment (VSE-OE)
• Software installation tools (Ignite-UX and Software Distributor-UX)
• System performance monitoring tools (GlancePlus, Measureware, OpenView Operations
Agent)
Applications do not have to be changed to run on a guest OS. Operating system patches and
hardware restrictions apply to guests.
Do not run the following types of applications on a guest:
• Integrity VM software
• Utility pricing tools (run on the VM Host)
• Capacity planning tools (run on the VM Host)
• Applications that require direct access to physical hardware (for example, disaster-tolerant
solutions)
• Multipath storage solutions
• SAN Management tools and applications that require access to serial interfaces (Integrity
VM virtualizes SCSI and Ethernet devices only)
• Auto port aggregation (APA)
You must purchase licenses for any software you run on a virtual machine, including the HP-UX
operating system and any HP or third-party layered software. You can purchase the licenses for
HP software under the HP Virtualization Licensing program. For more information, contact your
HP Support representative.
Always read the product release notes before installing any software product so that you have
the latest information about changes and additions to the documentation. The following chapters
describe how to install the Integrity VM software and how to create guests to run on the VM
Host system.
1.6 Do Not Install Applications on the VM Host System
When you install Integrity VM, HP-UX kernel parameters are changed to accommodate the
virtual machine environment. This makes the system unsuitable for running any other
applications. Regardless of whether guests are configured and running, the VM Host system is
not configured to allow applications to share system resources. You can run system management
utilities and 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
