HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide

release of the OS. If the virtual machine OS is Windows or Linux, install additional
AVIO-compatible drivers on the VM Host and virtual machine; the Windows and Linux
AVIO drivers include instructions for installing the drivers on virtual machines. In addition,
if the virtual machine OS is HP-UX, the AVIO components on the VM Host and virtual
machine should be from the same release of the OS; for example, both VM Host and virtual
machine should use the components from the same OE or from the same Web Release (for
example, WEB0803).
With HP Integrity VM, AVIO requires a vswitch that has a physical network device as the
backing device (local vswitches such as localnet are not supported). In addition, the physical
NIC that backs the virtual switch must have an AVIO-compatible driver.
For more information about AVIO requirements, see the HP Integrity Virtual Machines
Installation, Configuration, and Administration manual.
Create the virtual switch by performing the following steps:
1. (Required) Enter a virtual switch name.
• The name must be 8 characters or fewer.
• The allowable characters are A-Z, a-z, 0-9, dash (-), underscore (_), and period (.).
• The name cannot begin with a dash and cannot remain blank.
2. Specify the virtual switch type (whether it is to be dedicated or shareable). The default is
shareable.
NOTE: The terms "shareable" and "dedicated" refer to how the switch is assigned to the
virtual machines.
• A dedicated vswitch can be used by only one started virtual machine at a time and is
dedicated to providing network throughput to that virtual machine. More than one
virtual machine can have the same dedicated switch as a resource, but only one is
allowed to start.
• A shareable vswitch can be used at any given time by all the associated virtual machines
that contain the virtual network device (NIC) backed by a shareable vswitch.
NOTE: All virtual machines with virtual NICs backed by a shareable vswitch are not
required to be running. If you have a stopped virtual machine that uses the shareable
vswitch, you can always start the virtual machine (unless other problems prevent it
from starting).
3. (Required) From the table, select the VM Host's physical network device that will be the
physical backing of the vswitch.
Choices include the following:
• Any physical network cards (adapters) configured on the VM Host
• Any APA (Automatic Port Aggregation) configured on the VM Host
The display shows the APA name in one column and the individual devices or cards
in the next column; however, the letters "APA" do not appear in either column. In
HP-UX, any LAN port with port number 900 or greater is an APA (for example, lan900
or lan901).
• None
This creates a local vswitch. When no physical network device on the VM Host is chosen,
the vswitch is a local vswitch. A local vswitch has no connection with any physical
network device on the VM Host. Virtual machine virtual network interface cards (vNICs)
