[PATCH 03/10] schema-recipe: add support for veth interfaces

[Ondrej Lichtner]

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

This patch adds recipe XML support for veth interfaces. Since veth
devices are created in pairs, XML specification reflects this by
encapsulating two <veth> tags in a single <veth_pair> tag. Both of these
tags are mandatory. At the moment there are no <options> supported - you
can specify them, but they will be ignored.

Example interface specification would look something like this:

<interfaces>
    <eth id="out_if" label="tnet"/>
    <veth_pair>
        <veth id="testifc1" netns="xyz">
            <addresses>
                <address value="192.168.200.2/24"/>
            </addresses>
        </veth>
        <veth id="testifc2"/>
    </veth_pair>
    <bridge id="br">
        <slaves>
            <slave id="out_if"/>
            <slave id="testifc2"/>
        </slaves>
    </bridge>
</interfaces>
