Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

1. Take the download.sh file and put it into a directory where you want the files to be saved.
2. cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
3. Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

KVM

Lo primero que hay que entender es que para utilizar KVM tambien es necesario utilizar otras herramientas, las mismas son QEMU y Libvirt.

KVM (Kernel Virtual Machine), es un Hypervisor para Linux, gracias a ciertas funciones del kernel de Linux (y a las tecnologias de virtualizacion Intel VT-x y AMD svm) es posible virtualizar cualquier distro de Linux dentro de un Servidor Linux consumiendo muy pocos recursos.

Junto con KVMse suele instalar QEMU (Quick Emulator), que es un emulador y tambien virtualizador, que puede usarse en conjunto con KVM para administrar y crear VMs (Virtual Machines, KVM tambien las define como "Dominions"),se suele utilizar QEMU con KVM en principio porque suele ser mas sencillo de aprender a usar gracias a la interfaz grafica de QEMU, por otra parte, QEMU solo puede funcionar, pero siendo mucho menos eficiente al momento de consumir recursos (todo es
