Nova doesn't have maintainers in the same way as the Linux Kernel. However, we do have sub-teams who maintain parts of Nova and a series of nominated "czars" to deal with cross functional tasks. Each of these sub-teams and roles are documented on our wiki at https://wiki.openstack.org/wiki/Nova You can find helpful contacts for many parts of our code repository at https://wiki.openstack.org/wiki/Nova#Developer_Contacts We also have a page which documents tips and mentoring opportunities for new Nova developers at https://wiki.openstack.org/wiki/Nova/Mentoring Finally, you should also check out our developer reference at https://docs.openstack.org/nova/latest/contributor/index.html Thanks for your interest in Nova, please come again!
