HP Integrity Virtual Machines Manager 4.3 User Guide

components (such as drivers and libraries) on the virtual machine and VM Host be updated
to the latest 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.
For HP-UX, HP recommends that you install the latest AVIO components for both the VM Host
and the guest; however, updating both guest and host components at the same time is not
mandatory. Updating both components ensures that you always receive the latest bug fixes
for a complete solution. Always check the following software depot website for the latest
version of AVIO software (search for “HPVM AVIO”):
http://software.hp.com
Guest AVIO drivers are included in the VMGuestSW bundle available from the software depot
website. Make sure you install the latest version of that bundle.
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
documentation.
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.
