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.

Nesting virtual machines


It is possible to create a virtual cluster using a Proxmox hypervisor on top of an existing Proxmox cluster. Due to the performance drop of a nested hypervisor, the use case for a nested cluster is very limited. They can be used in, but are not limited to, the following scenarios:

  • Practice clusters in a classroom

  • Test clusters to test the latest software releases before applying them to real environments

  • Proof of concept clusters to test new configuration ideas

In this section, we will see how to enable the nested feature in Proxmox.

Getting ready

Deploying a nested virtual cluster is very different from deploying on true hardware. Make sure to plan ahead if the nested virtual cluster is going to be used on a physical Proxmox cluster. There must be adequate resources, such as CPU and memory available to support the actual and virtual nested clusters. The nested virtual host can quickly be starved of resources in such an environment since there is a lot overhead due to...
