Previous article: an introduction to XenServer
In the previous issue we have introduced the XenServer hypervisor and talked about its history, from the origin of the project up to now, then we’ve described its structure and operating mode. In this new article we’ll take a closer look at how to install and use it. The ISO image is available at this address, where you can also access to Software Development Kits, patches and documentation.
Like other hypervisors, there’s an HCL list with supported hardware, but for a testing purpose you can install Xen onto a whitebox with non-officially supported hardware: take care when choosing chipset and network cards (Intel IHC and Realtek NICs are to be preferred). Once the hardware and the ISO are ready, create a bootable USB drive (using free tools like UnetBootin or Rufus) and start the installation by selecting boot from such drive.
Xen, like VMware ESXi, is an hypervisor, that is, a software that allows to run several virtual machines -even with different operating systems, at the same time on the same hardware, sharing resources with the aim op optimizing costs and the management of the IT infrastructure. Given its nature, it’s often compared with concurrent platform by Microsoft (Hyper-V) and VMware (vSphere/ESXi), and in this article we are going to cover its characteristic.
A little bit of history
The Xen virtualization project was born in 2003 at the University of Cambridge as a research project. Within a few time XenSource was founded, before being acquired by Citrix in 2007, which keeps a free version but starts to develop a paid version. The project is backed by big players of the market like Intel, AMD, Cisco, Amazon, Google, Oracle, Samsung and Verizon.
In 2013 Xen became part of the Linux Foundation, and Citrix adopted an opensource licensing for its own XenServer product, then at version 6.2. The paid version, which included support and additional maintenance services, still remains.
