Using MacVTap instead of Open vSwitch
------------------------------------------
Security groups are not supported by the MacVTap agent. Due to that, devstack
configures the NoopFirewall driver on the compute node.
MacVTap agent does not support l3, dhcp and metadata agent. Due to that you can
chose between the following deployment scenarios:
Single node with provider networks using config drive and external l3, dhcp
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This scenario applies, if l3 and dhcp services are provided externally, or if
you do not require them.

Multi node with MacVTap compute node
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This scenario applies, if you require OpenStack provided l3, dhcp or metadata
services. Those are hosted on a separate controller and network node, running
some other l2 agent technology (in this example Open vSwitch). This node needs
to be configured for VLAN tenant networks.
For OVS, a similar configuration like described in the
:ref:`OVS Provider Network <ovs-provider-network-controller>` section can be
used. Just add the the following line to this local.conf, which also loads
the MacVTap mechanism driver:
::
[[local|localrc]]
...
Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch,linuxbridge,macvtap
...
For the MacVTap compute node, use this local.conf:
::
HOST_IP=10.0.0.3
SERVICE_HOST=10.0.0.2
MYSQL_HOST=10.0.0.2
RABBIT_HOST=10.0.0.2
