Sorry, I am wrong, and looks like this bug related to OpenVZ.

Second container with CentOS 7.2 + nginx 1.9.9 from official repo
and some result - nginx is down after reboot and errors in log.

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
and nginx failed because network interface is not available:

# cat /var/log/messages

after manually "systemd start nginx" all works fine.
also all works fine in other containers, not CentOS 7.2
