To create a vswitch, select Create
→Virtual Switch from the Integrity Virtual Server Manager menu.
This displays a page similar to that shown in
Figure 69 Create Virtual Switch page
The table on the screen shown in
displays the following information:
•
LAN interface: Shows the physical LAN interface to which a vswitch can be attached. The
“(none)” entry indicates that the vswitch is local, meaning that it not connected to a LAN
interface. Communication over such a vswitch does not go out on the physical network and
is useful only for communicating between VMs or vPars.
•
Used by: Shows all of the vswitches already configured to use the corresponding LAN interface.
A LAN interface can be used by only one vswitch at a time. You can configure multiple
vswitches that use the same LAN card, but only one of these switches can be active at one
time. In the row for creating a local vswitch [“(none)” entry], the Used by column lists all
existing local vswitches. All local vswitches can be active simultaneously. A new local vswitch
can be started regardless of the number of existing active local vswitches.
•
Hardware path: Shows the hardware path associated with the LAN interface.
•
Supports AVIO: Shows whether the physical backing device supports Accelerated Virtual
Input/Output (AVIO). For each VM or vPar containing an AVIO device, the VSP OS and the
guest OS must support AVIO. In addition, HP strongly recommends that AVIO components
(such as drivers and libraries) on the VM or vPar and VSP be updated to the latest release of
the OS. If the VM or vPar OS is Windows or Linux, install additional AVIO-compatible drivers
on the VSP and VM or vPar.
For HP-UX, HP recommends that you install the latest AVIO components for both the VSP and
the guest; however, updating both guest and VSP 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”):
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.
