### Fork the master linux Github repository
#### - Configured a linux kernel build (make config) using the cloned tree and built the kernel.
#### - Also installed any required initrd/initramfs.

#### - Encountered “Makefile” error during configuring a linux kernel build.
#### - Installed any relevant modules (e.g : libncurses-dev, pkg-config)
#### - Configure was successful after installing necessary dependencies and modules.

#### - After that, I configured initrd.img using the “mkinitramfs” command.

### Boot into the test kernel and modify the KVM code:
#### - After rebooting, ensure the system successfully boots into the newly built kernel.
#### - Use the uname -r command to check the current kernel version and verify that it matches the one you installed.
#### - Then, locate the __vmx_handle_exit function in the arch/x86/vmx/vmx.c file and implement code to count total_exit and exit type accordingly.

#### - After that, rebuild the kernel using make -j$(nproc), then run make_modules and make modules_install to install the KVM module. 
#### - Finally, reboot the system to test the changes.
