Qubes Overview

Qubes is an open-sourced, security-centric operating system. Qubes effectively utilizes Xen-based virtualization for the creation of isolated virtual machines using Paravirtual (PV) or Hardware Virtual Machine (HVM) virtualization. These virtual machines (VMs), referred to as “qubes,” aim to decrease the damage done if one of them becomes compromised by dividing them into separate security domains.  For example, you would have a separate qube (VM) for insecure browsing, another for work-related tasks, and personal use and data, with each one  having its assigned level-of-trust. Some other features offered include:

  • Use of multiple operating systems (Debian, Fedora, and Windows 7)
  • Creation of disposable VMs
  • Whonix integration
  • Private key security with Split GPG

Install the Operating System on the Vault

Once the Qubes installation image is properly burned to the USB drive, it is ready to be installed on the Vault.

  • Verify the Vault is powered down.
  • Verify the monitor is connected.
  • Verify the USB keyboard is plugged in.
  • Verify an Ethernet connection is in the “WAN” port that is connected to a DHCP server.
  • Insert the USB install drive into the other USB port on the Vault.
  • While powering up the Vault, press “F11” key until it boots to the BIOS and you see the boot options screen.
  • Select the USB drive to boot from.
  • On the boot screen, select the Test this media & install Qubes option.
  • On the installer screen appears, select your language preference.
  • On the Installation summary screen, select appropriate installation configuration settings for Localization, Software, and System for installation destination. Select Done after making selections.
  • Enter a passphrase for disk encryption.
