[libvirt-users] Libvirt adds extra parameters in domain XML

Hello, In my C++ code, I generate my own domain XML file and I use virDomainCreateXML or virDomainDefineXML to launch my qemu VM. However, when I get to check which commands are sent to the qemu commandline, I find that libvirt has added so many extra parameters to the ones I have already set. How can I prevent libvirt from adding any extra parameters to the ones I originally defined in the domain XML? Help will be highly appreciated. Thanks
