Virtualization is the latest buzz word. You may wonder computers are getting cheaper every day, why should I care and why should I use virtualization? Virtualization is a broad term that refers to the abstraction of computer resources such as:
- Platform Virtualization
- Resource Virtualization
- Storage Virtualization
- Network Virtualization
- Desktop Virtualization
This article describes why you need virtualization and list commonly used FOSS and proprietary Linux virtualization software.
VirtualBox is a virtual emulator like VMWare workstation. It has many of the features VMWare has, as well as some of its own.
I really like new Opensource VirtualBox from Sun. It is light on resources. Here is a quick tip – you can convert a VMware virtual machine (image) to a VirtualBox machine (image) using qemu-img utility, without reinstalling the GUEST operating system
In this second part you will learn about creating user accounts, SKEL directory and virtual hosting configuration under chrooted Apache jail.
A chroot on Red Hat / CentOS / Fedora Linux operating changes the apparent disk root directory for the Apache process and its children. Once this is done attacker or other php / perl / python scripts cannot access or name files outside that directory. This is called a “chroot jail” for Apache. You should never ever run a web server without jail. There should be privilege separation between web server and rest of the system.
In this exclusive series, you will learn more about:
- Securing an Apache 2 web server under Red Hat Enterprise Linux / CentOS Linux using mod_chroot
- Virtual hosting configuration
- Troubleshooting Chrooted Apache jail problem.
The Linux Foundation is launching a video contest and you can win yourself a trip to Tokyo next year to participate in the Linux Foundation Japan Linux Symposium Oct, 2009.
If you’ve been alive and aware of mass media over the last twelve months, you’ve probably seen television commercials from Apple and Microsoft touting their operating system. From Apple’s ubiquitous “I’m a Mac” to Jerry Seinfeld to Microsoft’s “I’m a PC” retort, operating system commercials have been flooding the airways. Except one OS has been notably absent — Linux.
You can upload your contest video here.

Excellent article, I couldn’t agree more with author. From the blog post:
My advice is to to speak up for Linux and promote unity in the Linux community. It is okay to have friendly rivalry between distros, but we need to guard against larger and more insidious forces attacking from the outside, and to protect that which we have in common. If Linux is going to change let it be from the inside out.
