Hello everyone!!

I have just deployed my first CentOS 6.5 instance inside my openstack icehouse but I am not able to login thourgh console (I need to do it because it has got a graphical installation). I have being testing some points but I am not able to find the problem. Could u help me?

PD1: my openstack installation is "allinone"

*I am using a company proxy too to connect to internet if that matters.
