Virtual Interfaces extension#
A virtual interface works in the same way as the network interface card (NIC) inside your laptop. Like a NIC, a virtual interface is the medium through which you can attach a network. To use a virtual interface to attach a network to your server, you create and connect a virtual interface for a specified network to a server instance. The network, which is comprised of logical switches, is attached to your server instance through the virtual interface.
You can create a maximum of one virtual interface per instance per network.
When you delete a virtual interface, the associated network is detached from the server instance. Also, if you want to delete an isolated network, the network cannot be attached to any server. Delete the virtual interface for the isolated network, and then you can delete the network.
