Google Cloud, Gnome via SSH

Question

Eu estou rodando o CentOS7 através do Google Compute e instalei o Gnome com sucesso via yum e tentando iniciar o console, mas retorna este erro:

xauth:  file /home/sublyime/.serverauth.7851 does not exist

(EE) 
Fatal server error:
(EE) PAM authentication failed, cannot start X server.
        Perhaps you do not have console ownership?
(EE) 
xinit: giving up
xinit: unable to connect to X server: Network is unreachable
xinit: server error
Couldn't get a file descriptor referring to the console

Idéias?
