The Opencloud Cloud Services user interface supports network configuration for virtual machine instances based on the following general networking concepts:

Subnets — A standard IP subnet based on the IP address and mask.

Network Interfaces — A network interface is simply a specific IP address assigned to virtual machine instances. To maintain network consistency, a network interface can be defined as an IP address in a specific subnet. The user interface ensures that the selected IP address is in the selected subnet.

Creating Network Interfaces

To define a network interface:

1. Go to Network > Network Interfaces.
2. In the top toolbar, click Create.

In the Create Elastic Network Interface dialog box, enter the following:

• Name — the name of the network interface.
• Description — an optional description of the network interface.
• VPC — the VPC to which the network interface should be assigned.
• Subnet — select from an existing subnet configured for the VPC, or define a new subnet to be added to the VPC.
• Private IP Address — select a private IP address from the subnet defined above.
• Security Groups — select a security group to manage traffic on the network interface.

Network Interface Operations

After creating the network interface, it will appear in the list of network interfaces in the Networking > Network Interface view. The following operations can be performed by selecting the network interface from the list and clicking the corresponding icon.

From the top toolbar:

• Edit — to change the name of the network interface.
• Security Group — to change the security group associated with the network interface.
• Delete — to delete the network interface.
• Detach Subnet — to detach a specific network interface from the virtual machine instance.
