The main reason was anĪntiquated tool that everyone had to use on Windows for kernel debugging. It literally saved me a ton of time for debugging my code.īut still, kernel debugging was lagging, even in the VM. Then at around year 2010 or so, developers got a pleasant surprise in the form of virtualization, or virtual machines (or VMs.) I immediately jumped on board and has been So coupled with the need for frequent reboots, slow POST times and you got yourself quite an uncomfortable work environment.Now you're literally faced with a dial-up speed of such connection. But even if you got to the next stage, and connected your two PCs via an antiquated COM port,. Even if you managed to connect a second PC, you're immediately faced with a host of connectivity issues and no logging to understand what went wrong and why.Not many people can just whip out a second PC and connect it to their main one. And unless you live in a computer-repair bunker (like OSR folks) You can't do full-fledged kernel debugging on one computer, thus you're forced to use a second PC.Like I pointed out above, there are quite a few issues that developers and reverse-engineers face while doing kernel debugging in Windows. Guest VM is having 100% CPU utilization when breakpoint is activated.Disassembly window shows "garbage" after triggering breakpoint.Breakpoint freezes up or BSODs guest OS.Registers pane shows incorrect register values.WinDbg Preview fails to connect to guest OS.To Disable Kernel Debugging of Guest OS.Network Connection Settings in WinDbg Preview.Configure Guest OS For Network Kernel Debugging.So it sounds like I need a table of contents for it: This blog post turned out to be a whopper. In this blog post I will try to demystify the intricacies of installation and setup of a Windows kernel debugger.Īnd, for those that don't like reading through long blog posts, make sure to check my video recap at the end. Thus, no wonder, there are so few people who understand and do kernel debugging well. And piled on top of that,Įven the installation of your workbench system for kernelĭebugging is in no way easy, either. And it doesn't help that most tools for kernel debugging in existence today are designed in a very poor style,Īre very costly, and are lacking basic features that we take for granted in pretty much any other software. Kernel debugging of any kind is not for the faint of heart.
