| 7 | <p>Virtual Distributed Ethernet (VDE) is a flexible, virtual network infrastructure system, spanning across multiple
|
|---|
| 8 | hosts in a secure way. It enables L2/L3 switching, including spanning-tree protocol, VLANs, and WAN emulation. It
|
|---|
| 9 | is an optional part of <ph conkeyref="vbox-conkeyref-phrases/product-name"/> which is only included in the source
|
|---|
| 10 | code. </p>
|
|---|
| 11 | <p>VDE is a project developed by Renzo Davoli, Associate Professor at the University of Bologna, Italy. </p>
|
|---|
| 12 | <p>The basic building blocks of the infrastructure are VDE switches, VDE plugs, and VDE wires which interconnect the
|
|---|
| 13 | switches. </p>
|
|---|
| 14 | <p>The <ph conkeyref="vbox-conkeyref-phrases/product-name"/> VDE driver has a single parameter: VDE network. This is
|
|---|
| 15 | the name of the VDE network switch socket to which the VM will be connected. </p>
|
|---|
| 16 | <p>The following basic example shows how to connect a virtual machine to a VDE switch. </p>
|
|---|
| 17 | <ol>
|
|---|
| 18 | <li>
|
|---|
| 19 | <p>
|
|---|
| 20 | Create a VDE switch:
|
|---|
| 21 | </p>
|
|---|
| 22 | <pre xml:space="preserve">vde_switch -s /tmp/switch1</pre>
|
|---|
| 23 | </li>
|
|---|
| 24 | <li>
|
|---|
| 25 | <p>
|
|---|
| 26 | Configure VMs using the command-line:
|
|---|
| 27 | </p>
|
|---|
| 28 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic<x> generic</pre>
|
|---|
| 29 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-generic-drv<x> VDE</pre>
|
|---|
| 30 | <p>
|
|---|
| 31 | To connect to an automatically allocated switch port:
|
|---|
| 32 | </p>
|
|---|
| 33 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-property<x> network=/tmp/switch1</pre>
|
|---|
| 34 | <p>
|
|---|
| 35 | To connect to a specific switch port
|
|---|
| 36 | <varname>n</varname>:
|
|---|
| 37 | </p>
|
|---|
| 38 | <pre xml:space="preserve">VBoxManage modifyvm "VM name" --nic-property<x> network=/tmp/switch1[<n>]</pre>
|
|---|
| 39 | <p>
|
|---|
| 40 | This command can be useful for VLANs.
|
|---|
| 41 | </p>
|
|---|
| 42 | </li>
|
|---|
| 43 | <li>
|
|---|
| 44 | <p>
|
|---|
| 45 | (Optional) Map between a VDE switch port and a VLAN.
|
|---|
| 46 | </p>
|
|---|
| 47 | <p>
|
|---|
| 48 | Using the switch command line:
|
|---|
| 49 | </p>
|
|---|
| 50 | <pre xml:space="preserve">vde$ vlan/create <VLAN></pre>
|
|---|
| 51 | <pre xml:space="preserve">vde$ port/setvlan <port> <VLAN></pre>
|
|---|
| 52 | </li>
|
|---|
| 53 | </ol>
|
|---|
| 54 | <p>VDE is available on Linux and FreeBSD hosts only. It is only available if the VDE software and the VDE plugin
|
|---|
| 55 | library from the VirtualSquare project are installed on the host system. </p>
|
|---|
| 56 | <note>
|
|---|
| 57 | <p>For Linux hosts, the shared library libvdeplug.so must be available in the search path for shared libraries. </p>
|
|---|
| 58 | </note>
|
|---|
| 59 | <p>For more information on setting up VDE networks, please see the documentation accompanying the software. See also
