Folks,
Here is another problem I'm stuck with.
Would love to see if I could do Host/Target with KDP based debugging !
Any suggestion, please ?

On 10.10 I have the corresponding xnu source that I can now build ( both
DEBUG and RELEASE). I uses Fusion, so taking snapshot of the running VM
instance is not a problem, and I wanted to drop the kernel.debug to
/Systems/Library/Kernel directory, named it as kernel, and boot from there.
Since the KDP based LLDB is working when I try to connect from the host
while I'm running the original OS version ( with or without the
corresponding Kernel Debug Kit), I was hoping that in case of a
continuous panic while trying to boot, I should be able to connect from
the host.
But the problem is that while the boot messages comes to the screen, it
tells that both ip and mac addresses are 0s. Like 0.0.0.0 and
00:00:00:00:00:00. And I can not connect. I looked the debug.c and kdp.c
code, there seem to be some variables related to ip etc., that are being
set to 0s as default. Not sure if I could hard code them based on what
have from the original setup, and that would work or not.
If not, then how could I setup KDB/DDB using either nvram or using the
com.apple.Boot.plist. I know this should give me just the single VM
debugging !!
