Thanks Martin. What I would like to achieve is govern the interface name created within the container, so that my application can take different actions on different interfaces (such as eth0, eth1 etc.,).
Libvirt's lxc driver seems to create interfaces as eth0, eth1 and so on, when there are multiple <interface /> entries in the domain xml. How can I request for a particular interface name?
I saw that in some of the examples in https://libvirt.org/formatdomain.html, <source dev=" " network=" "> is specified. I tried setting the "dev" attribute of source tag, but it doesn't look like that is being parsed and stored either.

Hello
I am trying to create interfaces within an LXC container with specific
name. I am using the following XML:
<interface type='network' name='blah'>
<source network='dpbr_n_0'/>
</interface>
That name='' is not parsed, it won't get saved, it doesn't mean
anything to libvirt. This particular configuration doesn't say much,
because type=network means all the settings will get set from the
network dpbr_n_0. See https://libvirt.org/formatdomain.html for all
the things you can configure in <interface/> and what does each option
mean.
This doesn't seem to work; it always ends up creating interface with name
as "eth0".
I found some examples here:
http://libvirt.org/guide/html/Application_Development_Guide-Network_Interfaces-XML_Format.html
That uses interface type as "ethernet" and specifies name also, If I do
that, I get back an error while starting the container as "Unsupported
network type ethernet".
Appreciate your help.

Harish
