Hello, in an interactive shell, I can successfully execute such a command: add network --name brv13 --vlan-id 13 --datacenter-identifier Cines --description A_FORM but the same as an argument of ovirt-shell, # ovirt-shell -E "add network --name brv13 --vlan-id 13 --datacenter-identifier Cines --description A_FORM" it leads me to "datacenter Cines does not exist." of course, datacenter Cines does exist! What's wrong there? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
