Mastering Proxmox - Second Edition

By: Wasim Ahmed

Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features to manage virtual machines, to be used for storage, and to virtualize both Linux and Windows application workloads. You begin with refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. You then move on to explore Proxmox under the hood, focusing on the storage systems used with Proxmox. Moving on, you will learn to manage KVM Virtual Machines and Linux Containers and see how networking is handled in Proxmox. You will then learn how to protect a cluster or a VM with a firewall and explore the new HA features introduced in Proxmox VE 4 along with the brand new HA simulator. Next, you will dive deeper into the backup/restore strategy followed by learning how to properly update and upgrade a Proxmox node. Later, you will learn how to monitor a Proxmox cluster and all of its components using Zabbix. By the end of the book, you will become an expert at making Proxmox environments work in production environments with minimum downtime.

Managing an LXC container


In Proxmox, each LXC container has two configuration files. One defines the raw resource allocation while the other used by Proxmox is used to define a container. The Proxmox container configuration file can be found at the following location:

/etc/pve/local/lxc/<container_id>.conf

For our example container ID #101, the following are the contents of this configuration file:

The raw container configuration file can be found at

/var/lib/lxc/<container_id>/config.

The following is the content of the resource allocation configuration file for our example container:

There is another directory for the root filesystem that is a mount point for the allocated storage space inside the container. The location of the directory is as follows:

/var/lib/lxc/<container_id>/rootfs/

But in Proxmox, this directory is not used to store container data. For local storage, the container virtual disk image is created in:

/var/lib/vz/images/<container_id>/.

For shared storage...
