In this chapter, we are going to take an in-depth look at how we can create a virtualized network within a virtual environment. We will learn what the network building blocks are that make up the Proxmox hypervisor and how it manages both internal and external network connectivity. We will examine several network diagrams to see how Proxmox can be utilized to create an entire colony of virtual machines connected with virtual networks. We will also take a look at the Open vSwitch implementation in Proxmox along with the network configuration file, network bonding, VLAN, and so on. We can create dozens of virtual machines at will, but without a planned network model, we will fail to run an efficient virtual environment. If we compare virtual machines with bricks as building blocks, then it is the virtual network that acts as mortar to create anything from a hut to a cathedral.
In this chapter, we will cover the following topics:
