Xv6_systemcall

Xv6 is an operating system developed by MIT for the learning purpose. It is an implementation of the Unix version 6 using ANSI C language for x86 platforms. It is a great resource for learning operating systems and many universities all over the world have already used it in their courses.

Here's how to run xv6 operating system on a QEMU virtual machine simply on top of a 64-bit Ubuntu 14.04 LTS machine. First, You have to install some tools and packages on our Ubuntu Linux system as follows.

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install gcc-multilib
sudo apt-get install qemu
sudo apt-get install git

Then clone the git

git clone https://github.com/C-Society/Xv6_systemcall.git

cd Xv6_systemcall

Change the privilages of file sign.pl

Chmod 770 sign.pl

As I have already done all the required things.Time to compile and run xv6 system on QEMU emulator.

make make qemu

Now a new Qemu window will open. Type command

ls

It will list all the commands. So basically I have included 2 programs in it.

  1. User defined program first_program whose output is

"Hello world this is our first program on Xv6"

  1. System call getyear whose output is

"The year in which the UNIX version of Xv6 is designed"
