Feature pages are design documents that developers have created while collaborating on oVirt.

Most of them are outdated, but provide historical design context.

They are not user documentation and should not be treated as such.

Documentation is available here.

Vdsm python3 compatibility


Python 3 is already 5 years old and the pioneering distributions such as Arch Linux have been running with it as default Python interpreter for quite some time. Soon the turn will come for Fedora, which is one of the community supported distributions of oVirt.

The goal of this page is to drive VDSM and it’s components to become a single codebase that supports:

  • Python-2.6 (Could probably be eventually dropped when we make the next major version).
  • Python-2.7
  • Python-3.3+


  • Name: Antoni Segura Puimedon (APuimedo)

To help us achieve that, this page will keep links to some useful resources and a list of things ported and to port.
