Add this toy example I wrote somewhere for error handling

#include <stdio.h>

#define FAILURE 1
#define SUCCESS 0

#define DEBUG_ERROR(fmt, args...) fprintf(stderr, "ERROR: %s:%d:%s(): " fmt "\n", \

There are a lot of ways to create a virtual machine using kvm in linux. I will introduce the one I think is the most convenient.

Assumptions:

1. Ubuntu 14.04 or later.
2. Native system (physical machine).

Step by Step:

1. install qemu-kvm, libvirt-bin and check if hardware supports the necessary virtualization extesions for KVM.
