My standard configuration for Windows 8.1 is to boot my VMWare virtual machines under the boot debugger (winload.exe) via a pipe-based serial connection to permit loading the virtualkd extension module (which isn’t signed and won’t load otherwise absent manual intervention). I’m finding that the Windows 10.0.10240.9 kernel debugger is not working properly in my environment for doing this - it hangs. The Windows 10 debugger is working fine once the VM is up and running - just not for the boot debug step.
Has anyone else observed this issue? I haven’t seen this listed as a restriction for the Windows 10 debugger.
In the interim, I’ve found that using the downlevel debugger for the boot debugger with the current debugger for the VM seems to work, so this isn’t a critical issue. Just a curiosity.

I have only failed trying to get virtualkd 2.8 to work with Windows 10, even with manual intervention. The vmmon64.exe running on a 64bit Windows 10 host notices the 64bit Windows 10 vm starting in VMare Workstation 11.1.2b2780323, but never launches my WinDbg:10.0.10240.9 AMD64 debugger. If I click ?Run debugger? in vmmon64.exe windbg merely sits at ?Waiting to reconnect?? while the Windows 10 vm completes its boot.
All works fine when I launch a 64bit Windows 8.1 vm, same setup.
I am suffering debugging over ethernet from a bridged networking vm. If there are any tips or such you could share (either about virtualkd or something better than the network debugging transport), I am all ears (well, and a bit of soul-crushing despair).
Thanks,
David
Hello,
The KD interface has changed in Windows 10 and therefore kdbazis.dll that comes with VirtualKD isn’t working and you need to wait for a new version. Here is workaround that works but it’s not as user friendly as vminstall.exe
