Windbg with VPC or VMWARE

Anyone having experience with using windbg together with recent versions of
VirtualPC or VMWare? I remember VPC was not all that happy with debugging
before Microsoft got hold on it, but not sure about the present state.

I am very “happy” to hear about eventually problems and things not working,
and which of them is best suited at the moment for debugging.

I’ve been using VMWare for a while now with good luck. I’ve even done
back-to-back vmwares - one side for test, the other for kd. Not as
speedy as a real serial port in my experience, but works well. A
friend uses two vmwares on linux, back-to-back, for his windows
development, and it seems to work for him, though it’s not for
everyone. :slight_smile:

I have used all three potential products for debugging - VMWare, Virtual
PC, and Virtual Server. All work, although all of them have their
little quirks.

I have use windbg with VPC and it works fine. The only problem is if I type
.reboot. I have to stop and restart windbg even with the reset command in
the command line. Also you can’t start windbg until the VPC starts the VM.

Ken: I am not having any of those issue with VPC 2004. I start WinDbg like
this:

“C:\Program Files\Debugging Tools for Windows\windbg.exe” -k
com:pipe,port=\.\pipe\vpc_com_1,reconnect

I’ve used WinDbg with VMWare Workstation 4.05 per the directions at
http://silverstr.ufies.org/lotr0/windbg-vmware.html. It works some of the
time, but getting WinDbg & VMWare in sync is a bit of a challenge; it often
takes several restarts of VMWare to get WinDbg to connect to it.

I haven’t tried VPC, nor have I tried using VMWare with the latest version
of WinDbg; it may be that the new WinDbg doesn’t have the timing issues I
mentioned above.

The latest 4.x version of VMWare and the latest released version of Windbg
work fine. Just start the VMWare VM and stop at the boot.ini. Change the
startup time to -1 so it will not boot automatically. Then start Windbg,
then start the OS. Sometimes it may need a Ctrl+Alt+R to resync and get it
working. I occassionally have to end Windbg and restart it.

Wow, neat trick! I never knew about -1. Thanks.

I used VMWare 4.5 and it crashed sometimes when two virtual machines
are connected. But it works fine with VMWare 5.0.

I make use of VMWare’s snapshot feature. Have a basic OS (with /debug in
boot.ini and without your driver under test), capture the snapshot, make
sure you revert to snapshot while restarting.

Now all you have to do is start and stop the machine (no reboot
required) and you always start from a clean state. I am using VMWare 4.0

I made the changed “resets=0” to “reconnect” and it works!

Thanks!
