Configure multi-vNIC for Ubuntu instances

For Ubuntu instances to use multiple vNICs, the network interfaces must be configured within the operating system.

Complete the following steps to configure the network interfaces:

1. Log in to the Ubuntu instance and become root.
2. Run the following command:

   ip a

3. Make note of the interface names.
4. Edit /etc/network/interfaces:

   Repeat the lines for the primary interface, replacing the interface name with that of the secondary interface. For example, to enable interface ens4 add the followiong lines:

   auto ens4iface ens4 inet dhcp

5. Run the following command:

   service networking restart

Note

These instructions will bring up the network interfaces and allow them to receive IPs. If additional networking configuration is desired, refer to the Ubuntu documentation
