Never modify that file beyond declaring a hook, it's a really bad idea for a prod environment. Again, openstack realm is to create an XML file that is passed to libvirt and no more. OpenStack only creates and deletes instances it's not his responsibility to modify it on runtime, that's libvirt resoonsability and if you want to do it there are 2 ways: Create an extension api for openstack that connects via python to the libvirt on the compute nodes. Or call to the libvirt API directly via shell and modify the instance.
