VirtualKD between two virtual machines

[Anonymous]

Hi,

I have a linux host OS in which I have my Win7 dev VM and my Vista test machine.
My current setup involves using the virtual serial port between the two VMs to debug.

My question is: Does VirtualKD work between two virtual machines as in my setup?

No, but you can try redirecting the host-side named pipe to the other VM using the GuestRPC protocol (http://articles.sysprogs.org/kdvmware/guestrpc.html). (You’ll need to modify the sources)

I’m in a similar position. Not using Linux as host OS but Windows 7 though.
I’ve got the following setup:
Host (vmware): Windows 7
Dev Machine (virtual machine #1): Windows XP
Test Machine (virtual machine #2): Windows XP
I use debugport=COM1 in the debug settings in boot.ini on the Test Machine, and using a named pipe from the Dev Machine as \hostpipecom_1 to connect from the Dev Machine to the Test Machine with WinDbg.
The named pipe from the Test Machine (configured in the vmware settings) creates the named pipe from the virtual machine to the host machine, so I need to connect from the dev machine to the host machine as well to reach the named pipe.
I haven’t been able to get VisualDDK to work yet in this setup, and according to your reply, it will never work?
Will this setup get supported in the future?

For linux I have a working solution: http://blog.adjimann.com.ar/2011/06/virtualkd.html
You must change VBoxDD.so and then it sends the packets over udp to a proxy running in the windows guest that runs the debugger.

Hi bazis,

the given link above won’t work:

Does it moved to another location?

I’ve the same situation with the following configuration:
Host: Win7x64 Ultimate with VMWare Workstation
VM1: WinXP Prof+VS2008 for development
VM2: Win7x64 Prof as driver target

I’ll try to have a closer look to “redirecting the host-side named pipe to the other VM using the GuestRPC protocol”.
Maybe you have more information about this topic in the meanwhile?
