[libvirt] How to add custom tag to the libvirt xml file for a new feature of the VM

[Yashwanth K P]

Hello,

I am working on libvirt development and I wanted to add a custom tag to 
the libvirt xml to add a new feature to the VM. I am having trouble 
getting started with this. It would be really helpful if you can help me 
get started with this and guide me on what part of the source code that 
has to be modified to achieve the goal.

Thanks in advance.

Regards,
