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.,).
<interface> <guest dev='devicename'/> </interface> That is what you're looking for. Although I usually recommend not relying on the name, but rather using the MAC address. Also <target dev='othername'/> says how the device will be named on the host.
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.

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 nameas "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".
