Test kernel changes in a matter of seconds using Rapido - a glorified wrapper for Dracut and QEMU. This talk will walk through the process of taking a kernel source repository and turning it into a testable VM. For those who would like to play along on their own machine, please bring: - a laptop with openSUSE Leap or Tumbleweed installed - Kernel source (mainline master) After covering a simple standalone test procedure, the walk-through will then move on to kernel testing alongside network accessible storage such as iSCSI, and also touch on some debugging techniques.
