Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I was compiling for about 20 minutes and then stoped and I got this error:
make: se sale del directorio `/root/kernel_compiling/linux-184.108.40.206'
/usr/bin/make -j2 ARCH=i386 \
make: se ingresa al directorio `/root/kernel_compiling/linux-220.127.116.11/Documentation/lguest'

make: se sale del directorio `/root/kernel_compiling/linux-18.104.22.168/Documentation/lguest'

*se ingresa al directorio = Inserting in the directory
*No existe el fichero o el directorio = Doesnot exist a file or directory
*se sale del directorio = Leaving the directory
Google this error message:
> lguest.c:21:25: error: sys/eventfd.h: No such file or directory
and the first link  has a solution:
"Below “Virtualization” unselect “Linux hypervisor example code” or if
you need lguest you can also fix the compilation error by removing
“#include <sys /eventfd.h>” (line 21) from lguest.c."
But where to unselect?
Below the Virtualization? Where is it?
I just dont understund.
Distribution: pclos2016, Slack14.1 Deb Jessie, + 50+ other Linux OS, for test only.
I guess, you can edit "Virtualization" in the file .config
( or just redo your configuring. )
Finding "Virtualization" in .config :
grep -in Virtualization .config
( the option n gets the line number ).
Example from my /boot/config :
grep -in Virtualization config :
4093:# CONFIG_VIRTUALIZATION is not set
.... the line mumber is 4093 .
So when you find your "Virtualization" line, probably change to :
# CONFIG_VIRTUALIZATION is not set
