You can find presentations on slideshare and videos on vimeo. We will also embedded both in the agenda. The slides are also available for download as zip file.

From printk to QEMU: Xen/Linux Kernel debugging

Current experience shows that a lot of developers working on Xen/Linux kernel use mainly only small set of debugging tools. Often they are sufficient for generic work. However, when unusual problem arises which could not be easily debugged using known tools sometimes they are trying to reinvent the wheel. Goal of this session is to present wide range of debugging tools starting from simplest one to most feature reach solutions in context of Xen/Linux kernel debugging. It will describe pros and cons of printk (serial, debug console, etc.), gdb, gdbsx, kgdb, QEMU, kdump and others. Additionally, there will be some information about possible new solutions and current kexec/kdump developments for Xen.
