KGDB: use kgdb over the serial consoleīuild your kernel and install the modules like you would any other kernel.Īdd kgdboc=ttyS0,115200 to the kernel paremeters (ttyS depending on which COM port you choose in the VM setup.)Ĭopy the vmlinux (uncompressed version to the host machine).Īlso copy the. KGDB: kernel debugging with remote gdb -> Build the kernel with debug symbols, kgdb support, sysrq keys Install VirtualBox with a VM containing the kernel you want to debug. This will become the virtual serial console that gdb connects to on the host machine. Give a path to the file on the host where you want the pipe. You can check the box to have VirtualBox create the pipe too. When setting up the VM, add a serial port and set it to use Host Pipe. So here is how I set things up on my Linux host machine to debug a target Linux kernel running in a VirtualBox VM. There wasn’t a single source with all the information I needed to get set up and working though. I found a few different pages with information on debugging a Linux kernel with kgdb.
