Figure 63 Create virtual switch
The table on the screen shown in Figure 63 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 virtual partitions.
• 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 virtual partition containing an AVIO device, the VSP OS and
the guest OS must support AVIO. With HP Integrity VM, AVIO requires a vswitch that has a
physical network device as the backing vehicle (local vswitches are not supported). The physical
NIC that backs the virtual switch must have an AVIO-compatible driver. HP strongly recommends
that AVIO components (such as drivers and libraries) on the virtual partition be updated to
the latest release of the OS.
For Windows and Linux guests, support for AVIO virtual network devices requires that
compatible Windows and Linux drivers be installed on the guest and additional patches be
installed on the Integrity VM version 3.5 or later.
For HP-UX, HP recommends that you install the latest AVIO components for both the VSP 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.
For more information about AVIO requirements, see the HP Integrity Virtual Partitions
documentation.
