This is used to link the pipe file (FIFO) that is created by VirtualBox, with a pseudo-terminal on the host system.

#HOW TO INSTALL GDB ON ORACLE VIRTUALBOX SERIAL#

A virtual serial port is enabled between the host and the guest. When we combine VirtualBox with KGDB on a single machine, the host OS is the ‘source’ machine, while the guest OS (Linux kernel compiled with KGDB enabled) is the “destination”. With virtualisation, however, we can do away with that second machine. However, since version 2.6.26, KGDB has been merged into the mainline, and only needs to be enabled during kernel compilation.Ī typical KGDB setup requires two machines connected by a serial cable: one as a source machine on which debugging is done, and the other (destination) which is being debugged. Earlier, KGDB used to be a bunch of patches that had to be carefully merged into the mainline kernel. It can debug the kernel while it is running, set breakpoints, and step through the code. KGDB is an amazing Linux kernel debugging tool.

Readers are expected to have prior knowledge on how to use GDB, know the fundamentals of the Linux kernel, understand custom compilation, apart from knowing how to use VirtualBox or any other virtualisation software. This article shows how to use virtualisation atop a running OS to help debug a live kernel on a single machine.

Download Windows version from here as I will be using Windows 10 to install VirtualBox.Debugging an application live has always been easy for application developers, but debugging a live kernel has never been a simple option for kernel developers - it involves multiple machines with serial connections. VirtualBox can be installed in Linux based operating systems such as Ubuntu, centOS etc., MacOS and Windows. You can download VirtualBox from the official Oracle VirtualBox website. Please visit the official page to find out the list of supported Operating Systems that can be Installed in VirtualBox. Please refer to my post to know more about it. On a related note, Microsoft provides its own version of Hypervisor or Virtualization application called Hyper-V.Please refer to my post which will show you how to enable Virtualization technology in Windows.To find out if you computer supports Virtualization technology please refer to my post here.Please refer to some of my post to know more about Virtualization. But with VirtualBox, to use CPU based Virtualization technology, Virtualization technology has to be enabled through BIOS for Intel based processors. When the CPU has support to Virtualization Technology, the virtualization is said to be hardware-based or hardware-assisted.īoth VMware Workstation and Oracle VirtualBox take advantage of Virtualization technology to improve performance. With them, controlling software (called VMM, Virtual Machine Monitor) can be simpler, thus improving performance compared to software-based solutions. The advantage is that, CPUs with Virtualization Technology have new instructions to control virtualization. These days most of the processors, both from Intel and AMD comes with CPU based Virtualization technology. You can also view my video on YouTube on this topic.

#HOW TO INSTALL GDB ON ORACLE VIRTUALBOX 64 BIT#

VirtualBox supports both 32 bit and 64 bit version of the various operating systems currently available. Oracle VirtualBox is a virtualization software that allows you to run multiple Operating system on your host operating system without having the need to dual boot your computer. In this blog post, I will show you how to install Oracle VirtualBox 6.1.6 on Windows 10 along with Extension Pack.
