Cómo montar un cluster de flexVDI con DRBD (sin almacenamiento compartido)

flexvdi+drbd
Habitualmente, para montar un cluster de flexVDI, es necesario disponer de un almacenamiento compartido con disco directo (una SAN FC o SAS).

Este almacenamiento compartido se emplea para almacenar la imagen de flexVDI Manager (el orquestador de la plataforma), las plantillas de escritorio y los diferenciales de los escritorio no volátiles.

De los tres elementos mencionados, el único que genera una carga de disco significativa es el último, los diferenciales no volátiles (las plantillas de escritorio, generalmente, se encuentran cacheadas en memoria del Host, gracias al sistema de caché de flexVDI). Por tanto, si estamos pensando en montar un sistema de VDI donde la mayor parte de las escritorios van a ser de tipo volátil, podemos plantearnos prescindir del almacenamiento compartido, sustituyéndolo por un sistema de almacenamiento definido por software, como DRBD.

Enabling HYP mode on the Raspberry Pi 2

The newest iteration of the wonderful machine designed by Raspberry Pi Foundation, the Raspberry Pi 2, sports a Broadcom BCM2836 SoC, with four Cortex-A7 cores. The Cortex-A7, being the little brother Cortex-A15, features the ARM Virtualization Extensions, so both Xen and KVM based virtualization should work on it.

At this point, you probably are wondering why would someone want to use virtualization on a RPi2. In addition to the usual “because you can!” answer, there’s a pretty good reason for it. Imagine you want to use the RPi2 as a media center and, at the same time, you want to run some personal services (like ownCloud or Pydio) on it. Instead of polluting the media center image, you can run an isolate, secure, virtual machine for such purpose. And, using my VEXPRESS_KVM port, you can even provide those services running NetBSD! 😉

The first step towards being able to use virtualization on the Raspberry Pi 2, is finding a way to boot the kernel in HYP mode. Let’s see how can we do that.
