HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

• Running vPars/VMs with DIO as Serviceguard nodes
• Support for HP-UX network providers
NOTE: The direct I/O networking functionality is not currently supported with the HP Auto Port
Aggregation (APA) product.
For more information about using direct I/O networking, see “Using direct I/O networking” (page

1.8 Running applications in vPars or Integrity VM environments
The VSP is the manageability platform for vPars or VMs. Though VSP runs the standard HPUX OE,
it is a controlled environment, and no customer applications are to be installed or run on the VSP.
Customer applications are to be run on an individual VM or vPar.
The following sections provide details of what can be run on the VSP as well as on the individual
vPar or VM. The VSP system runs the Integrity VM or vPars software, which is responsible for
allocating processor and memory resources to the running guests. The VSP system can run physical
resource, performance, and software management and monitoring tools. To allow the VSP to
allocate resources to the virtual environments, do not run end-user applications, such as database
software, on the VSP system. Instead, run them in virtual environments.
Typical software you can run on the VSP system includes the following:
• HP-UX 11i v3 Virtual Server Operating Environment (VSE-OE)
NOTE: vPars and Integrity VM V6.1 is included in the HP-UX VSE-OE, as well as the in the
HP-UX DC-OE. You can install vPars and Integrity VM from the OE and run them on the VSP
system. If you have purchased the HP-UX VSE-OE or the DC-OE, you are also entitled to run
that OE on the VSP and the vPars and VM.
For information about the software that is required on the VSP system, see Chapter 4 (page 43).
• Software installation tools (Ignite-UX and Software Distributor-UX)
• Hardware diagnostic and support tools to monitor guests (WBEM, online diagnostics, Instant
Support Enterprise Edition [ISEE])
• 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 virtual machines or vPars are running, do not run other applications on the
VSP system. Examples of applications that should not be run on the VSP are: Oracle, Workload
Manager (WLM), HP SIM, and so forth. HP-UX vPars and Integrity VM installation modifies kernel
parameters, making the system unsuitable for running applications.
An OS running in a virtual environment 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 in a virtual environment includes the following:
