This patch adds support for Linux Bridges to os-net-config. This is
done completely with ifcfg files, brctl is not used directly.
Hierarchy is preserved, so a Linux Bridge may have a Linux Bond
as a member, which in turn may have multiple interfaces as members.
This changeset has been updated to include a more specific example
for Linux bridge configuration (that doesn't combine bridging and
bonding).
This change depends on the change to add support for Linux Bonds.

This change adds support for Linux Bonding to the impl_ifcfg
in os-net-config. This change adds support for configuring Linux
Bonds using the Bonding module rather than Open vSwitch. Most of
the options for Linux Bonds are the same as OVS, with the exception
of bonding_options instead of ovs_options.

When multiple interfaces are configured with DHCP, and more than
one interface receives a gateway from the DHCP server(s), the
resulting default gateway on the system is unpredictable. This
change adds the "defroute" boolean to the configuration syntax
for os-net-config. Any interface type may be marked so that the
gateway received from the DHCP server will not be eligible as a
default gateway for the system. This only works for ifcfg files,
/etc/network/interfaces lacks an equivalent option.

This adds the option to permanently rewrite the configuration so the
aliases are used instead of the system name. This is useful where
you have a variety of hardware and you want to have consistent device
naming accross all platforms - this allows you to essentially rename
the interfaces permanently so they match the abstracted nicN names.
Note, this needs to be run with --cleanup or the old (now conflicting)
configs will still be in place, and it may require a reboot before
the changes are fully applied.

Currently there's a fixed mapping between abstracted interface
names (nic1, nic2 etc) and the underlying biosdevname for the
device.
In many cases, this mapping based on system enumeration is
sufficient, but in some cases, particularly when you perform
detailed pre-deployment discovery of interfaces, you may wish
to alter the mapping independently of the config (e.g if the
config is in a heat template, and the discovery data is
provided at runtime).
So this adds a -m option to os-net-config, which enables a
mapping file to be provided, such that specific interfaces
may be mapped to their abstract names based on knowledge of
the devices or the networks they are connected to.
The mapping file has the following format, where em1 and em2 are
device names as detected by the OS (e.g biosdevname):
interface_mapping:
nic1: em2
nic2: em1
Or you can use the device MAC instead:
interface_mapping:
nic1: 12:34:56:78:9a:bc
nic2: 12:34:56:de:f0:12

Adds a simple example showing how an individual interface can be
configured, e.g outside of a bond etc.

Updates the object model so that a VLAN on top of a bridge
(an OVS int port) doesn't require a physical device to
be set in the object model.
|
|
Adds new YAML examples. Also adds some new CLI test
cases which compare --noop stdout (from the CLI) for
the json and yaml examples to verify they generate
the same things.
