I made some changes in config and it works fine. One more thing I wanted to ask is I want to add an attribute to xml. But I am not able to figure out how exactly libvirt is defining xml. I understand that config can only add the attributes that are defined in the xml. But how do I add a new attribute?</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif;
