Using DevStack with neutron Networking
|
|
======================================
|
|
|
|
This guide will walk you through using OpenStack neutron with the ML2
|
|
plugin and the Open vSwitch mechanism driver.

|
|
|
Using Neutron with a Single Interface
|
|
=====================================
|
|
|
|
In some instances, like on a developer laptop, there is only one
|
|
network interface that is available. In this scenario, the physical
|
|
interface is added to the Open vSwitch bridge, and the IP address of
|
|
the laptop is migrated onto the bridge interface. That way, the
|
|
physical interface can be used to transmit self service project
|
|
network traffic, the OpenStack API traffic, and management traffic.
|
|
|
|
|
|
.. warning::
|
|
|
|
When using a single interface networking setup, there will be a
|
|
temporary network outage as your IP address is moved from the
|
|
physical NIC of your machine, to the OVS bridge. If you are SSH'd
|
|
into the machine from another computer, there is a risk of being
|
|
disconnected from your ssh session (due to arp cache
|
|
invalidation), which would stop the stack.sh or leave it in an
|
|
unfinished state. In these cases, start stack.sh inside its own
|
|
screen session so it can continue to run.
|
|
|
|
|
|
Physical Network Setup
|
|
----------------------
|
|
|
|
In most cases where DevStack is being deployed with a single
|
|
interface, there is a hardware router that is being used for external
|
|
connectivity and DHCP. The developer machine is connected to this
|
|
network and is on a shared subnet with other machines. The
|
|
`local.conf` exhibited here assumes that 1500 is a reasonable MTU to
|
|
use on that network.
|
|
|
|

|
|
|
|
The following is a complete `local.conf` for the host named
|
|
`devstack-1`. It will run all the API and services, as well as
|
|
serving as a hypervisor for guest instances.

Adding Additional Compute Nodes
|

|
|
|

Let's suppose that after installing DevStack on the first host, you
|
|
also want to do multinode testing and networking.

devstack-2 [ address = "172.18.161.7" ];
|
|
}
|
|
}
|
|
|
|
|
|
After DevStack installs and configures Neutron, traffic from guest VMs
|
|
flows out of `devstack-2` (the compute node) and is encapsulated in a
|
|
VXLAN tunnel back to `devstack-1` (the control node) where the L3
|
|
agent is running.

`br-int` is a bridge that the Open vSwitch mechanism driver creates,
|
|
which is used as the "integration bridge" where ports are created, and
|
|
plugged into the virtual switching fabric. `br-ex` is an OVS bridge
|
|
that is used to connect physical ports (like `eth0`), so that floating
|
|
IP traffic for project networks can be received from the physical
|
|
network infrastructure (and the internet), and routed to self service
|
|
project network ports. `br-tun` is a tunnel bridge that is used to
|
|
connect OpenStack nodes (like `devstack-2`) together. This bridge is
|
|
used so that project network traffic, using the VXLAN tunneling
|
|
protocol, flows between each compute node where project instances run.
|
|
|
|
|
|
|
|
DevStack Compute Configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The host `devstack-2` has a very minimal `local.conf`.
|
|
|
|
::
|
|
|
|
[[local|localrc]]
|
|
HOST_IP=172.18.161.7
|
|
SERVICE_HOST=172.18.161.6
|
|

|
## Neutron options
|
|
PUBLIC_INTERFACE=eth0
|
|
ENABLED_SERVICES=n-cpu,rabbit,q-agt
|
|
|
|
Network traffic from `eth0` on the compute nodes is then NAT'd by the
|
|
controller node that runs Neutron's `neutron-l3-agent` and provides L3
|
|
connectivity.
|
|
|
|
|
|
Neutron Networking with Open vSwitch and Provider Networks
|
|
==========================================================
|
|
|
|
In some instances, it is desirable to use neutron's provider
|
|
networking extension, so that networks that are configured on an
|
|
external router can be utilized by neutron, and instances created via
|
|
Nova can attach to the network managed by the external router.
|
|
|
|
For example, in some lab environments, a hardware router has been
|
|
pre-configured by another party, and an OpenStack developer has been
|
|
given a VLAN tag and IP address range, so that instances created via
|
|
DevStack will use the external router for L3 connectivity, as opposed
|
|
to the neutron L3 service.
|
|
|
|
Physical Network Setup
|
|
----------------------
|
|
|
|
.. nwdiag::
|
|
|
|
nwdiag {
|
|
inet [ shape = cloud ];
|
|
router;
|
|
inet -- router;
|
|
|
|
network provider_net {
|
|
address = "203.0.113.0/24"
|
|
router [ address = "203.0.113.1" ];
|
|
controller;
|
|
compute1;
|
|
compute2;
|
|
}
|
|
|
|
network control_plane {
|
|
router [ address = "10.0.0.1" ]
|
|
address = "10.0.0.0/24"
|
|
controller [ address = "10.0.0.2" ]
|
|
compute1 [ address = "10.0.0.3" ]
|
|
compute2 [ address = "10.0.0.4" ]
|
|
}
|
|
}
|
|
|
|
|
|
On a compute node, the first interface, eth0 is used for the OpenStack
|
|
management (API, message bus, etc) as well as for ssh for an
|
|
administrator to access the machine.
|
|
|
|
::
|
|
|
|
stack@compute:~$ ifconfig eth0
|
|
eth0 Link encap:Ethernet HWaddr bc:16:65:20:af:fc
|
|
inet addr:10.0.0.3
|
|
|
|
eth1 is manually configured at boot to not have an IP address.
|
|
Consult your operating system documentation for the appropriate
|
|
technique. For Ubuntu, the contents of `/etc/network/interfaces`
|
|
contains:
|
|
|
|
::
|
|
|
|
auto eth1
|
|
iface eth1 inet manual
|
|
up ifconfig $IFACE 0.0.0.0 up
|
|
down ifconfig $IFACE 0.0.0.0 down
|
|
|
|
The second physical interface, eth1 is added to a bridge (in this case
|
|
named br-ex), which is used to forward network traffic from guest VMs.
|
|
|
|
::
|
|
|
|
stack@compute:~$ sudo ovs-vsctl add-br br-ex
|
|
stack@compute:~$ sudo ovs-vsctl add-port br-ex eth1

Service Configuration
|
|
---------------------
|
|
|
|
**Control Node**
|
|
|
|
In this example, the control node will run the majority of the
|
|
OpenStack API and management services (keystone, glance,
|
|
nova, neutron)
|
|
|
|
|
|
**Compute Nodes**
|
|
|
|
In this example, the nodes that will host guest instances will run
|
|
the ``neutron-openvswitch-agent`` for network connectivity, as well as
|
|
the compute service ``nova-compute``.
|
|
|
|
DevStack Configuration
|
|
----------------------
|
|
|
|
.. _ovs-provider-network-controller:
|
|
|
|
The following is a snippet of the DevStack configuration on the
|
|
controller node.
|

## Neutron Networking options used to create Neutron Subnets
|
|
|
|

|
|
PROVIDER_SUBNET_NAME="provider_net"
|
|
PROVIDER_NETWORK_TYPE="vlan"
|
|
SEGMENTATION_ID=2010
|
|
|
|
In this configuration we are defining FIXED_RANGE to be a
|
|
publicly routed IPv4 subnet. In this specific instance we are using
|
|
the special TEST-NET-3 subnet defined in `RFC 5737 <http://tools.ietf.org/html/rfc5737>`_,
|
|
which is used for documentation. In your DevStack setup, FIXED_RANGE
|
|
would be a public IP address range that you or your organization has
|
|
allocated to you, so that you could access your instances from the
|
|
public internet.
|
|
|
|
The following is the DevStack configuration on
|
|
compute node 1.
|
|
|
|
::
|
|
|
|
HOST_IP=10.0.0.3
|
|
SERVICE_HOST=10.0.0.2
|

|
|
|
|
## Open vSwitch provider networking options
|
|
PHYSICAL_NETWORK=default
|
|
OVS_PHYSICAL_BRIDGE=br-ex
|
|
PUBLIC_INTERFACE=eth1
|
|
Q_USE_PROVIDER_NETWORKING=True
|
|
|
|
Compute node 2's configuration will be exactly the same, except
|
|
``HOST_IP`` will be ``10.0.0.4``
|
|
|
|
When DevStack is configured to use provider networking (via
|
|
``Q_USE_PROVIDER_NETWORKING`` is True) -
|
|
DevStack will automatically add the network interface defined in
|
|
``PUBLIC_INTERFACE`` to the ``OVS_PHYSICAL_BRIDGE``
|
|
|
|
For example, with the above configuration, a bridge is
|
|
created, named ``br-ex`` which is managed by Open vSwitch, and the
|
|
second interface on the compute node, ``eth1`` is attached to the
|
|
bridge, to forward traffic sent by guest VMs.
|
|
|
|
Miscellaneous Tips
|
|
==================
|
|
|
|
Non-Standard MTU on the Physical Network
|
|
----------------------------------------
|
|
|
|
Neutron by default uses a MTU of 1500 bytes, which is
|
|
the standard MTU for Ethernet.
|
|
|
|
A different MTU can be specified by adding the following to
|
|
the Neutron section of `local.conf`. For example,
|
|
if you have network equipment that supports jumbo frames, you could
|
|
set the MTU to 9000 bytes by adding the following
|
|
|
|
::
|
|
|
|
[[post-config|/$Q_PLUGIN_CONF_FILE]]
|
|
global_physnet_mtu = 9000
|
|
|
|
|
|
Disabling Next Generation Firewall Tools
|
|
----------------------------------------
|
|
|
|
DevStack does not properly operate with modern firewall tools. Specifically
|
|
it will appear as if the guest VM can access the external network via ICMP,
|
|
but UDP and TCP packets will not be delivered to the guest VM. The root cause
|
|
of the issue is that both ufw (Uncomplicated Firewall) and firewalld (Fedora's
|
|
firewall manager) apply firewall rules to all interfaces in the system, rather
|
|
then per-device. One solution to this problem is to revert to iptables
|
|
functionality.
|
|
|
|
To get a functional firewall configuration for Fedora do the following:
|
|
|
|
::
|
|
|
|
sudo service iptables save
|
|
sudo systemctl disable firewalld
|
|
sudo systemctl enable iptables
|
|
sudo systemctl stop firewalld
|
|
sudo systemctl start iptables
|
|
|
|
|
|
To get a functional firewall configuration for distributions containing ufw,
|
|
disable ufw. Note ufw is generally not enabled by default in Ubuntu. To
|
|
disable ufw if it was enabled, do the following:
|
|
|
|
::
|
|
|
|
sudo service iptables save
|
|
sudo ufw disable
|
|
|
|
Configuring Extension Drivers for the ML2 Plugin
|
|
------------------------------------------------
|
|
|
|
Extension drivers for the ML2 plugin are set with the variable
|
|
``Q_ML2_PLUGIN_EXT_DRIVERS``, and includes the 'port_security' extension
|
|
by default. If you want to remove all the extension drivers (even
|
|
'port_security'), set ``Q_ML2_PLUGIN_EXT_DRIVERS`` to blank.
|
|
|
|
|
|
Using Linux Bridge instead of Open vSwitch
|
|
------------------------------------------
|
|
|
|
The configuration for using the Linux Bridge ML2 driver is fairly
|
|
straight forward. The Linux Bridge configuration for DevStack is similar
|
|
to the :ref:`Open vSwitch based single interface <single-interface-ovs>`
|
|
setup, with small modifications for the interface mappings.

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
