Figure 60 Create Virtual Switch page
The table on the screen shown in Figure 60 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 machines.
• 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 machine containing an AVIO device, the VM Host OS
and the guest OS must support AVIO. In addition, HP strongly recommends that AVIO
