SELinux blocks name_connect neutron-metadata on port 8775. The result is user vm instances cannot start up or you cannot ssh to them. Port 8775 is used by the neutron metadata agent. https://github.com/openstack/neutron/blob/master/etc/metadata_agent.ini

COMMAND=ssh -o BatchMode=yes -o StrictHostKeyChecking=no fedora.2.46 ls
OUTPUT=Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
