What Internship Programs is the Xen Project participating in Summer 2018?

The Xen Project Advisory Board has funding for interns for Outreachy this summer (formerly known as the GNOME Outreach Program) which runs from May 2018 to August 2018. The project will also apply as mentoring organisation for GSoC 2018.

  • Outreachy helps people from groups underrepresented in free and open source software get involved in open source projects. Our goal is to increase the participation of underrepresented groups in the Xen Project. For more information see 2018 May-August Xen Project approved projects

How To Apply to GSoC

We will provide more information related to GSoC, if the project is accepted as GSoC mentoring organization.

However, the following information applies generally

  • Start engaging with the developer community as early as possible
  • Join the xen-devel@, mirageos-devel@, ... mailing list depending on the project you choose (check the table below). Please do no contact mentors privately - open source is about openness: use the mailing lists and CC the mentor(s) AND
  • Check whether you have all the hardware you need to participate (see table below).
  • Try to build the project (e.g. Hypervisor, Mirage OS, Unikraft, ...) from source and run it
  • Get yourself a suitable starter project (see Internships/Make a Small Contribution Requirement and table below). Although GSoC does nor require a starter project, you will compete with applicants who will do so.
  • Join the IRC channel on related to the table below. Please do not join the channel, ask a question and then leave again without leaving some contact details: you won't see the reply and we wont be able to contact you.
  • Familiarise yourself with our GSoC_Student_Application_Template, such that you know what information you need to provide
  • Make the application via
