OVH VPS - firewalld не работает в Centos 7

Я установил новый сервер на OVH с CentOS 7:

yum install firewalld  

затем включил и перезагрузил

systemctl enable firewalld   
reboot

Теперь я могу войти в систему с помощью ssh, но firewalld не появляется

[root@~]# firewall-cmd --state
failed

[root@~]# firewall-cmd --get-default-zone
<empty line>
[root@~]# firewall-cmd --get-active-zones
<empty line>
[root@~]# systemctl status firewalld

Hint: Some lines were ellipsized, use -l to show in full.

Если я попробую сделать следующее, я все равно получаю ошибки:

[root@/]# firewall-cmd --zone=public --change-interface=eth0
Error: 'filter'

Как я могу это решить ???
