Overview of this book

Proxmox VE's intuitive interface, high availability, and unique central management system puts it on par with the world’s best virtualization platforms. Its simplicity and high quality of service is what makes it the foremost choice for most system administrators. Starting with a step-by-step installation of Proxmox nodes along with an illustrated tour of Proxmox graphical user interface where you will spend most of your time managing a cluster, this book will get you up and running with the mechanisms of Proxmox VE. Various entities such as Cluster, Storage, and Firewall are also covered in an easy to understand format. You will then explore various backup solutions and restore mechanisms, thus learning to keep your applications and servers safe. Next, you will see how to upgrade a Proxmox node with a new release and apply update patches through GUI or CLI. Monitoring resources and virtual machines is required on an enterprise level, to maintain performance and uptime; to achieve this, we learn how to monitor host machine resources and troubleshoot common issues in the setup. Finally, we will walk through some advanced configurations for VM followed by a list of commands used for Proxmox and Ceph cluster through CLI. With this focused and detailed guide you will learn to work your way around with Proxmox VE quickly and add to your skillset.

Configuring a bridge


In this recipe, we are going to see what a bridge is in Proxmox networking, and how to configure it to create a virtual network of VMs.

Getting ready

A bridge is a virtual implementation of a physical network switch. Virtual machines can be connected to a bridge much in the same way that a physical computer can be connected to a network switch to communicate with other network devices. The naming term for a bridge interface is vmbrX, where X can be an integer number from 0 to maximum of 4096. By default, a new Proxmox installation creates a bridge named vmbr0 in each node.

Each bridge can be attached to a physical network interface of a node or without it. A bridge configured without any physical network interface cannot direct traffic outside the node itself. The traffic can only flow in between whichever VMs are connected to this physical interfaceless bridge. The following diagram shows a network diagram of a bridge with and without a physical network interface:
