UserModeLinux (UML) was one of the first virtualization technologies for Linux, also known as "a port of Linux to its own user space ABI". Currently almost everyone is using KVM, XEN or VMware to virtualize Linux. But UML still exists and has users. Richard observed that many kernel developers have no clue how UML works and therefore break it from time to time without even noticing.

In this talk he gives an overview of UML and its internals. The key points are:
  • Why UML has still users and what the use cases are
  • How to build and test it
  • On which other sub systems it depends (and how it can break)
  • How it works
  • Emerging new features like SMP support and x86-compat mode
  • Limitations and problems of the current implementation
  • Discussion with other kernel developers how Richard can help that UML does not hinder others work
