Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

The Proxmox HA simulator


Although Proxmox HA has become far easier to configure and manage, it is still a complex topic to grasp. With the use of software-based watchdogs, it is entirely possible to configure, test, and learn Proxmox HA in a virtualized environment before implementing it in a production cluster. There is also a simulator for Proxmox HA that we can use to see HA in action without setting up any clusters. The simulator allows us to see the HA configuration in action and see how the states change at different stages.

Configuring the Proxmox HA simulator

The Proxmox HA simulator is not shipped with the distribution and needs to be manually installed. Along with the simulator package, we also need xorg and xuath because the simulator requires X11 redirection, which is also known as X11 forwarding. We can use the following commands to install the packages:

# apt-get install pve-ha-simulator# apt-get install xorg# apt-get install xauth

We can access the simulator from both Linux and...
