I’m using VirtualKD to debug a virtual machine running under vmware. The debugger successfuly attaches but I cannot break-in to kd using combination. Instant break button from VirtualKD as well as or combinations work as expected. If I start kd.exe from command line, works.
Maybe, it’s related to the way child processes are created. Try making a batch file that starts KD using “start” command and tell VMMON to use it (the “custom:” radio button).
