Problem while debugging driver on win 7

WINDBG
1

Hi,

I am new to driver development and trying to learn it by debugging the
sample driver codes. Also, I am new to OSR online so kindly excuse me for
any unintentional mistake.

I was debugging driver on vmware with host OS and guest OS as win xp and it
was working fine but now when i try to debug it with host OS as win 7 64
bits Home premium and win xp(32 bits) as guest operating system windbg fails
to connect to xp.

I learned to debug driver on vmware from the following link:
http://silverstr.ufies.org/lotr0/windbg-vmware.html

Please note that this worked fine when guest and host OS both were win xp.
Kindy help if you have any idea.

Thanks,
Saurabh Dhir

Are you starting vmware & windbg using ‘Run as Administrator?’

Hi,

I am running x86 win xp vmimage(target machine) on top of x64 win 7(host
machine). I have modified the boot.ini of the target machine as follows:

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=“Microsoft Windows XP
Professional” /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=“Microsoft Windows XP
Professional Debug” /noexecute=optin /fastdetect /debug /debugport=com1
/baudrate=115200

and using the following command line to run windbg and connect to target
machine’s kernel:
cd C:\WinDDK\7600.16385.1\Debuggers
windbg -b -k com:pipe,port=\.\pipe\com1,resets=0

I have also made the necessary changes to the serial port settings as
mentioned on this http://silverstr.ufies.org/lotr0/windbg-vmware.html
URL.

But despite doing all this I am unable to connect windbg of host machine to
connect to the kernel of target machine. I always get the folowing output
displayed on windbg:

Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64
Copyright (c) Microsoft Corporation. All rights reserved.

Opened \.\pipe\com1
Waiting to reconnect…

**

This is troubling me since many days and i have reinstalled the winddk also

to verify the installation. Any suggestion will be of great help.

* PS: I am opening windbg and vmware both as administrators.*

Thanks,
Saurabh

I highly recommend you to use VirtualKD http://virtualkd.sysprogs.org/ if
you are debugging via VMWare or VirtualBox.

Not only setup is done almost automaticlly, it much faster and remove the
COM port emulation bottle-neck.
