Well I have implemented the hyperv synthetic kernel debugger interface, but on Windows 10 it requires to have a working VMBus (it's not really using it, but without a function vmbus that will answer to the initiate contact then the kdnet will simply be stuck in a loop. With the synthetic kernel debugger interface you can debug older OS (Win7 up to latest Win10). The benefit is that its much faster than all other interfaces. In addition to that Michael Kelley from Microsoft has informed us that Microsoft might be dropped the synthetic kernel debugger interface sometime in the future, and it seems like the new mode is simply to use hvnet device for the communication (which is again much faster).
