Debug Learning Setup

WINDBG
1

Hope this question isn’t too out of scope for this digest, but I think if
anyone knows, it would be someone on this group.

I’m somewhat experienced in kernel debugging, but would like to improve my
skills. I’m in the process of setting up a debugging test bed at home, and
would like to kernel debug virtual machines running on either VMWare or
VirtualPC. I’ve found plenty of information on attaching WinDBG to
VMWare, but have found no information for debugging with VirtualPC. Does
anyone on this group have experience using VirtualPC for this purpose?
Does it work well for debugging purposes, or would I be better off using
VMWare?

Any feedback would be appreciated greatly.

I recently tried this with Virtual PC for Windows 5.1. You can hook the
guest OS’s COM port up to a physical COM port on the host machine. And
then you can debug through that. That means you’ll have to hook up a
null modem cable to the COM port and attach it to the debugger machine.

So one cool thing you can do is to use the null modem cable to attach 2
COM ports on the host OS. Then you can run your debugger on the host
and debug a guest OS.

The end result is you can debug fine, but still need the physical
linkup. You can do single machine debugging if the machine has at least
2 free COM ports.

BUT … you do not at that point have a multiprocessor machine. each virtual
machine will be a uni-processor – of course you could use the host as the
target and run WinDbg … ooops … what happens when you BP the host? :slight_smile:

My friend have tried Vmware, although I have not tried yet. He did kernel
debug VM.

This URL should help you.
http://www.vmware.com/support/ws3/doc/ws32_devices3.html

Point:
baudrate should not be high. 57600 is better.
