Learning Proxmox VE

Overview of this book

Proxmox VE 4.1 provides an open source, enterprise virtualization platform on which to host virtual servers as either virtual machines or containers. This book will support your practice of the requisite skills to successfully create, tailor, and deploy virtual machines and containers with Proxmox VE 4.1. Following a survey of PVE's features and characteristics,this book will contrast containers with virtual machines and establish cases for both. It walks through the installation of Proxmox VE, explores the creation of containers and virtual machines, and suggests best practices for virtual disk creation, network configuration, and Proxmox VE host and guest security.Throughout the book, you will navigate the Proxmox VE 4.1 web interface and explore options for command-line management

Ensuring hardware virtualization extensions are installed

Next, you'll want to ensure that hardware virtualization extensions are enabled on the intended Proxmox VE host.

Assuming there's no operating system on the machine, it's very simple to check this with a Ubuntu Desktop LiveCD. Follow these steps:

  1. Download the Ubuntu LiveCD image from http://www.ubuntu.com/download/desktop and burn it to a DVD.
  2. Boot the new machine from the Ubuntu LiveCD. (For more information on this process, visit https://help.ubuntu.com/community/LiveCD#How-To_LiveCD_Ubuntu.)
  3. Once the desktop is fully available, open the terminal emulator.
  4. For an Intel-based system, enter the following command in the terminal emulator: egrep -c '(vmx|svm)' /proc/cpuinfo.

If hardware virtualization extensions are enabled, as is the hope, this command should simply return an integer equal to the number of CPU cores in the machine. If the command returns a 0, hardware virtualization extensions must be enabled in the Intel system's EFI/BIOS...
