The following is a guide for deleting DomU virtual machines in Xen Project Hypervisor using xen-tools. Although xen-tools supports loopback, EVMS, and LVM partition types, this guide focuses on LVM-based DomU only. That being said, the information provided below may be easily adapted for use with loopback and EVMS-based DomU. If you’re looking for a […]

The threat of running unnecessary services on a system bloated with extra software is a less commonly discussed security concern. Yet enabled and listening services weaken the server’s defences by creating potential entry points for the attacker, as well as by providing resources for the attacker to use against other machines. The server hardening maxim we’re interested in today goes as follows: “Install only necessary software; delete or disable everything else.” With this topic in mind, our task is to examine how this technique applies to a Xen Project hypervisor DomU virtual machine running a paravirtualized Debian 9 operating system.
The purpose of this tutorial is to describe how to install and configure a Xen Project hypervisor with control and guest domains using Debian as the base operating system. Note that this tutorial uses Xen version 4.8.5-pre as included in the current stable release of Debian 9.5 (stretch).
