We currently do not use puppet-libvirt and qemu settings are managed via puppet-nova with augeas[0][1]. > * Other possibility is to configure the qemu.conf file directly using > the "init_setting" module like [4]. > > * Considering the move towards ansible, I would prefer if we can add > ansible based configuration along with docker-puppet for any new > modules going forward.

The problem with mixing both puppet and ansible is ensuring that only one owns the thing being touched. Since we use augeas in puppet-nova, this should not conflict with the usage of ini_setting with ansible. Unfortunately libvirt is not currently managed as a standalone service so perhaps it's time to evaluate how we configure it since multiple services (nova/ovs) need to factor into it's configuration.
