[CentOS] OpenVZ – container based virtualization quick guide. Part 1 of 2
+0 Vote Up -0Vote Down

This quick guide will walk you through setting up OpenVZ on CentOS. I followed these steps on CentOS release 5.5 x64 version. If you want more detail on install via different methods and/or have different flavor of CentOS and run into an issue, you can follow instructions provided by OpenVZ site. Once you are done with this guide, you will have CentOS container running for you to play with.

For my purposes, I started with very basic installation of CentOS 5.5. I have done this on existing installations of CentOS without any issues as well. Ok so let’s start with getting the OpenVZ repository added to our system. This means that we will be going down “yum” path instead of “rpm” path. This is the quickest and easiest way to get OpenVZ installed.

How to create a private cloud in your laptop
+4 Vote Up -0Vote Down
Everybody is moving to cloud architectures, although not all agree on what cloud computing is. In my limited understanding, and for the purpose of my work, cloud computing is a quick and versatile availability of virtual machines.
Now, if my purpose was deploying these machines, a private cloud in one host (namely, my laptop) would not make sense. But to create a flexible testing environment, it works very well.
Users of virtual machines software such as VMWare or VirtualBox may ask what's new here. You can create many virtual machines and use them within the same host.
True, but creating a new virtual machine in one minute without duplication of resources is not so easy. This is what this article

Drupal 7 test drive appliance updated to 7.0-beta2, now with GUI option
Employee +2 Vote Up -0Vote Down

Over the weekend I updated my Drupal 7 test appliance in SUSE Studio to the Drupal 7.0-beta2 release, which was released on Oct. 23rd. I also added phpMyAdmin upon a user request, to provide a web-based method to work with the MySQL instance, if needed.

In addition to the lightweight "headless" appliance (which can only be accessed and configured via a remote network connection), I've now also created a

Testing Drupal 7 on a virtual appliance with MySQL 5.1 and the InnoDB plugin
Employee +4 Vote Up -0Vote Down

The Drupal community just recently released another alpha test release of their upcoming Drupal 7 version, to shake out the remaining bugs and to encourage more users to test it.

If you would like to give it a try, but you don't have a free server handy, how about using a virtual machine instead? Using the fabolous SuSE Studio, I've created an appliance based on openSUSE 11.3, Drupal 7.0-alpha7 and MySQL 5.1 with the

No, DRBD doesn’t magically make your application crash safe
+4 Vote Up -0Vote Down

It is a common misconception that DRBD (or any block-level data replication) solution can magically make an application crash-safe that intrinsically isn’t. Baron highlights that misconception in a recent blog post.

I want to reiterate and stress that point here: if your application can’t reliably survive a node crash, it won’t successfully fail over on a replicated (or shared, for that matter) data device. But if it can, and DRBD is replicating synchronously, then DRBD won’t break it. In other words: try pulling the power plug on your machine while your app is running, and power back on. If your application recovers to a consistent state, you’re
