libvirt users - Aug 2013 - Adding network interfaces to VMs created on ESX hypervisor

Hi,

I want to create/attach two "internal" and one "host-only"
interface to my
node created by libvirt on ESX hypervisor.  Is it possible to do so?
If yes can anyone send a template of xml file?
If it is not possible then is there any alternative for this?

Regards,
Varun
