Ksplice on Ubuntu Installation: Video

With the recent acquisition of Ksplice by Oracle - I got to discover a really cool tool for Linux. Ksplice allows you to apply updates to a live running kernel without the need for rebooting your machine. Yeah right! That was my initial reaction too. But thanks to  some really smart guys from MIT Ksplice does just that. No need to reboot your linux kernel after an upgrade. Sounds too good to be true? Well the proof is in the pudding they say (I like the potato kind :) Well check out the video below to see how easy it is to setup and use Ksplice. For a quick overview of Ksplice check out the FAQ. If you want more details as to the inner workings read the whitepaper.

Ksplice is available on Oracle Linux via subscription through ULN. However it is free for Ubuntu Desktop and Fedora. This means that if you're running Red Hat Enterprise Linux or any other enterprise Linux flavor you're out of luck.

A few notes about installing Ksplice on Ubuntu

  • The installation was done on Ubuntu 11.04 - Natty Narwhal running in VirtualBox 4.12. The Ksplice documentation lists 10.04, 10.10 and 11.04 as being supported.
  • I chose the manual installation method after trying the GUI method and getting the error message seen below.

  • There is a ksplice package available via the Software Center in Ubuntu. DO NOT install this package. This provides the ksplice raw utilities which is not recommended for general use. This is a demo of the ksplice uptrack package instead.
  • You need to provide an email address for a key required to complete the installation.
Here is the demo
