I could use some help.

I’m working with Bootkits and want to debug a preboot environment of a VMWare machine. For some reason, I can’t get a proper connection with gdb.

Initially I was trying to use Ghidras debugger, but after being unsuccessful I decided to switch to gdb to try and narrow down potential problems.

I know the gdb stub is running on the target vm, because the logs say so. I can see packets being sent from gdb on my host machine. But my host machine never receives a response. I’ve tried with two different VMs. Windbg kernel debugging works over serial.

I’ve spent a day banging my head against this and could use some suggestions.
