Virtual Networks
Virtual Network enables a data center to provision the most suitable and efficient networking structure for the applications it hosts. And to alter that structure as conditions warrants, using software rather than requiring physical changes in connections to hardware.
Nodes have the actual bridges setup with physical network attached. Rio OS connects to virtual networks via API for setting up networking to cloud workloads.
Installation
Every node needs the software and bridge network to be setup.
A sample Ubuntu /etc/network/interfaces
In this example a bridge riopub is attached to physical port eth0.
nano /etc/network/interfaces
Copy & Paste the following.
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto riopub
iface riopub inet static
address 107.152.143.242
netmask 255.255.255.248
network 107.152.143.240
broadcast 107.152.143.247
gateway 107.152.143.241
# dns-* options are implemented by the resolvconf package, if installed
bridge_ports eno1
bridge_stp off
bridge_fd 0
bridge_hello 2
bridge_maxage 1
dns-nameservers 8.8.8.8
Save File using CTRL + X and then Y
Create a bridge and reboot system
sudo brctl addbr riopub && sudo reboot
Create Virtual Network
You must have the Netmask, CIDR and Gateway.
Rio OS automatically ignores the first IP and the last IP in the CIDR range.
Example:
Netmask = 255.255.255.248
Gateway = 107.152.143.241
CIDR = 107.152.143.240/29
The ip [107.152.143.240] is used as Network
The ip [107.152.143.241] is used as Gateway
The ip [107.152.143.242] is used as the node
The ip [107.152.143.247] is used as broadcast
Hence the usable ips are [107.152.143.243 - 107.152.143.246]
CLI
Refer Asciicast in cli.

The newly created virtual network is listed as below.
Rio OS automatically manages used and unsed ips of a virtual network from the range provided for a node.
The newly created virtual network is ready for selection during creation of Datacenters
