I'm really inclined to say that anyone wanting todo lock debugging should just use systemtap / dtrace todo it, since it is better in every way.
I tend to agree on that point, with one caveat - we need to have good documentation on how to do systemtap debugging of libvirt, in order to make it easy to point someone to the steps they need to follow to benefit from it. Our existing web pages on hacking are a bit sparse on this front.
OK, thanks for your input. My point was to enable this for people who don't want to (or can't) use systemtap for various reasons, but I guess nobody can be *that* lazy to do 'package_app install_command systemtap' and then cleanup afterwards. I like your idea of explaining systemtap debugging with libvirt on wiki/documentation. I'll try to combine it with additional systemtap examples and put it all together somehow. But I need you to check my grammar, since it tends to be a longer text. Thanks again and have a nice day, Martin
