<title>Configure Vif-plugging</title>
|
||||
<para>When nova-compute creates a VM, it "plugs" each of the VM's
|
||||
vNICs into an OpenStack Networking controlled virtual switch,
|
||||
and informs the virtual switch about the OpenStack Networking
|
||||
port ID associated with each vNIC. Different OpenStack
|
||||
Networking plug-ins may require different types of vif-plugging.
|
||||
You must specify the type of vif-plugging to be used for each
|
||||
<systemitem class="service">nova-compute</systemitem> instance
|
||||
in the <filename>nova.conf</filename> file.</para>
|
||||
<para>The following plug-ins support the "port bindings" API
|
||||
extension that allows Nova to query for the type of vif-plugging

required: <itemizedlist>
