Ktest.pl is a script that lives in the linux kernel source tree [ 1. That helps to automate this process. The script is extremely extensible and as such takes times to understand which variables need to be set and where. In this post, I'll go over how to perform a kernel bisection using a VM as the target machine. In this example I'm using 'ubuntu' as the VM name. Get an ap...

In order to setup crashdump, on an Ubuntu machine we can do the following. First we need to install and setup crashdump, more info can be found here [ 2. Sudo apt-get install linux-crashdump.

Monday, February 17, 2014. Creating a local vm domain from an ubuntu cloud image. It is very convenient to be able to quickly spin up a local VM in order to do some sort of bug verification or testing.
