Figure 4-4 Create Virtual Switch Page
The table on the screen shown in Figure 4-4 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
components (such as drivers and libraries) on the virtual machine be updated to the latest
