Hello,

Using the Sunstone GUI, we would like to let a user create a virtual network under the following conditions:

- The Network model should be limited to 802.1Q (our hosts are defined using this networking model).
- The Attribute “PHYDEV” should be hidden to the user, but contains a pre-defined value.

Do you see a possibility to achieve this with the current version of OpenNebula ?

Thank you very much in advance for your ideas.

Probably the closer to this request are VNET reservations, take a look at:
