Et voilà, mon noeud a été migré ! Accessible sur g1test.duniter.inso.ovh 
EDIT : Erf, en fait petit bug détecté :

Pour la configuration réseau suivante :
"remoteport": "80",
"ipv4": "127.0.0.1",
"ipv6": "::1",
"port": "8999",
"remotehost": "g1test.duniter.inso.ovh"
Le port 80 est celui de nginx, duniter devrait essayer d’écouter sur le port 8999… ?
