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 pushed further to create an entire colony of virtual machines connected with virtual networks. We will also look at the Proxmox 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 a good virtual environment. If we compare virtual machines with bricks as building blocks, then it is the network that acts as mortar to create anything from a basic hut to a cathedral.

In this chapter, we will cover the following topics:
