| 8 | Virtual Distributed Ethernet (VDE) is a flexible, virtual network
|
|---|
| 9 | infrastructure system, spanning across multiple hosts in a secure
|
|---|
| 10 | way. It enables L2/L3 switching, including spanning-tree protocol,
|
|---|
| 11 | VLANs, and WAN emulation. It is an optional part of <ph conkeyref="vbox-conkeyref-phrases/product-name"/>
|
|---|
| 12 | which is only included in the source code.
|
|---|

| 15 | VDE is a project developed by Renzo Davoli, Associate Professor at
|
|---|
| 16 | the University of Bologna, Italy.
|
|---|
| 17 | </p>
|
|---|
| 18 | <p>
|
|---|
| 19 | The basic building blocks of the infrastructure are VDE switches,
|
|---|
| 20 | VDE plugs, and VDE wires which interconnect the switches.
|
|---|
| 21 | </p>
|
|---|
| 22 | <p>
|
|---|
| 23 | The <ph conkeyref="vbox-conkeyref-phrases/product-name"/> VDE driver has a single parameter: VDE network.
|
|---|
| 24 | This is the name of the VDE network switch socket to which the VM
|
|---|
| 25 | will be connected.
|
|---|
| 26 | </p>
|
|---|
| 27 | <p>
|
|---|
| 28 | The following basic example shows how to connect a virtual machine
|
|---|
| 29 | to a VDE switch.
|
|---|
| 30 | </p>
|
|---|
| 31 | <ol>
|
|---|
| 32 | <li>
|
|---|
| 33 | <p>
|
|---|
| 34 | Create a VDE switch:
|
|---|
| 35 | </p>
|
|---|
| 36 | <pre xml:space="preserve">vde_switch -s /tmp/switch1</pre>
|
|---|
| 37 | </li>
|
|---|
| 38 | <li>
|
|---|
| 39 | <p>
|
|---|
| 40 | Configure VMs using the command-line:
|
|---|
| 41 | </p>
|
|---|
| 42 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic<x> generic</pre>
|
|---|
| 43 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-generic-drv<x> VDE</pre>
|
|---|
| 44 | <p>
|
|---|
| 45 | To connect to an automatically allocated switch port:
|
|---|
| 46 | </p>
|
|---|
| 47 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-property<x> network=/tmp/switch1</pre>
|
|---|
| 48 | <p>
|
|---|
| 49 | To connect to a specific switch port
|
|---|
| 50 | <varname>n</varname>:
|
|---|
| 51 | </p>
|
|---|
| 52 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-property<x> network=/tmp/switch1[<n>]</pre>
|
|---|
| 53 | <p>
|
|---|
| 54 | This command can be useful for VLANs.
|
|---|
| 55 | </p>
|
|---|
| 56 | </li>
|
|---|
| 57 | <li>
|
|---|
| 58 | <p>
|
|---|
| 59 | (Optional) Map between a VDE switch port and a VLAN.
|
|---|
| 60 | </p>
|
|---|
| 61 | <p>
|
|---|
| 62 | Using the switch command line:
|
|---|
| 63 | </p>
|
|---|
| 64 | <pre xml:space="preserve">vde$ vlan/create <VLAN></pre>
|
|---|
| 65 | <pre xml:space="preserve">vde$ port/setvlan <port> <VLAN></pre>
|
|---|
| 66 | </li>
|
|---|
| 67 | </ol>
|
|---|
| 68 | <p>
|
|---|
| 69 | VDE is available on Linux and FreeBSD hosts only. It is only
|
|---|
| 70 | available if the VDE software and the VDE plugin library from the
|
|---|
| 71 | VirtualSquare project are installed on the host system.
|
|---|
| 72 | </p>
|
|---|
| 73 | <note>
|
|---|
| 74 | <p>
|
|---|
| 75 | For Linux hosts, the shared library libvdeplug.so must be
|
|---|
| 76 | available in the search path for shared libraries.
|
|---|
| 77 | </p>

|
|---|
| 80 | For more information on setting up VDE networks, please see the
|
|---|
| 81 | documentation accompanying the software. See also
