Installing the System

Please refer to the section Troubleshooting if ever you have errors during the installation.

There are two official ways to install XiVO:

  • using the official ISO image

  • using a minimal Debian installation and the XiVO installation script

XiVO can be installed on both virtual (QEMU/KVM, VirtualBox, …) and physical machines. That said, since Asterisk is sensitive to timing issues, you might get better results by installing XiVO on real hardware.


By default XiVO installation will pre-empt network subnets and If these subnets are already used, some manual steps will be needed to be able to install XiVO. These steps are not described here.

Installing from the ISO image


Our ISO image does not support UEFI system

During the installation of Debian, only a proxy that supports proxying http/https requests may eventually be entered. Otherwise GPG key of XiVO repository will not be installed and must be added manually:

wget -O - | apt-key add -

Installing from a minimal Debian installation

XiVO can be installed directly over a 64-bit Debian 11 (Bullseye). When doing so, you are strongly advised to start with a clean and minimal installation of Debian Bullseye.

The latest installation image for Debian Bullseye can be found at


The installed Debian must:

  • not have caps in the hostname

  • use the architecture amd64

  • have a default locale en_US.UTF-8

  • use ext4 filesystem (for compatibility with docker overlay2 storage driver)

  • use legacy network interface naming eth#. To change the network interface naming to eth# use this procedure:

    • Edit /etc/default/grub, find line GRUB_CMDLINE_LINUX and set it to GRUB_CMDLINE_LINUX="net.ifnames=0"

    • Run update-grub

    • Edit interface names in /etc/network/interfaces

    • Reboot the machine



If your server needs a proxy to access Internet, configure the proxy for apt, wget and curl as documented in Proxy Configuration.

Once you have your Debian Bullseye properly installed, download the XiVO installation script and make it executable:

chmod +x

And run it:

./ -a 2022.10-latest

At the end of the installation, you can continue by running the configuration wizard.

Alternative versions

The installation script can also be used to install an archive version of XiVO (14.18 or later only). For example, if you want to install XiVO 2020.18-latest:

./ -a 2020.18-latest

When installing an archive version, note that:

  • versions 14.18 to 15.19 of XiVO can only be installed on a Debian 7 (wheezy) system

  • the 64-bit versions of XiVO are only available starting from 15.16

You may also install development versions of XiVO with this script. These versions may be unstable and should not be used on a production server. Please refer to the usage of the script:

./ -h

Other installation methods

It’s also possible to install XiVO by PXE. It is not documented here.
