This guide will walk you through the installation of the open source implementation of the Citrix XenCenter called OpenXenManager. The application is used as a graphical way to manage a Xen Hypervisor.


  1. First you need to install the Homebrew package manager. You can do this by executing the following in a terminal.
    /usr/bin/ruby -e "$(curl -fsSL"
  2. Update Homebrew like this: brew update && brew upgrade
  3. Install XQuartz: brew cask install xquartz
  4. Install the other dependencies: brew install python gtk pygtk FLTK
  5. Install TigerVNC: brew install
  6. Install configobj: pip install configobj
  7. Clone the latest OXM source.
    • mkdir ~/tmp
    • cd ~/tmp
    • git clone
    • cd openxenmanager
  8. Build OXM: python build
  9. Install OXM: python install
  10. Start OXM for the first time. After startup close it: /usr/local/bin/openxenmanager
  11. Modify the config file:
    • vi ~/.config/openxenmanager/oxc.conf
    • Find the vnc_viewer property and replace it’s value with: /usr/local/bin/vncviewer

OpenXenManager is now installed and ready for use. You can even use the remote console.

Known Bugs

  • The remote console closes with « unknown message » when the screen resolution changes (eg. when booting or installing Linux)
  • Some features of OpenXenManager are not yet implemented.
  • Exiting OXM takes a long time or doesn’t work
  • Changing a VM’s RAM value in the Settings works but it isn’t updated in the UI
