[Openstack] [Fuel] problem resolving node name only on ssh

Hi,

Sorry but this was not my issue. I completely deactivated the NM and still
have the same problem.

# service NetworkManager stop
Redirecting to /bin/systemctl stop  NetworkManager.service

I discovered the /etc/hosts was generated by puppet and has the good values.
The problem is that those 192.168.x.x interfaces cannot see each other on
deployed nodes. Meanwhile I did a dirty hack
I changed the /etc/hosts file just after puppet created them. Nevertheless
I would
like to understand why these 192.x.x.x interfaces cannot see each other.


Any help is welcome,
Pedro
