I recently set up Xen 3.0.3 on Debian etch using the great guide here from this site. However, if (like me) you use the binary Nvidia X.org driver rebooting into your new XenLinux kernel your X.org server will fail to start. If you read its error output, you will see that this is because it cannot find the nvidia kernel module. Here we'll show how to fix things.

The simple solution is to switch from the proprietary nvidia X.org driver to the nv driver. However, if (like me) you have become emotionally attached to the proprietary nvidia driver, then it is possible to make it work on a Xen kernel.

Contributing to open source software with Ian Varley of Salesforce

With open source, you're expanding the sphere of people who might potentially care a lot about your code. You find others who have similar problems, and who can leverage your work and maybe even extend it. The knowledge that you've helped someone avoid "rebuilding the wheel" is really gratifying, and it's amplified when those people actually start getting so involved that they give you contributions of code or ideas. The project picks up steam, and you might even get unforeseen help tackling those issues you didn't have bandwidth to tackle yourself. Really, it's the gift that keeps on giving. Read more
