If you have 4 GB or more RAM use the Linux kernel compiled for PAE capable machines. Your machine may not show up total 4GB ram. All you have to do is install PAE kernel package.

This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 6.0 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g.

So, you want to write a kernel module. You know C, you've written a few normal programs to run as processes, and now you want to get to where the real action is, to where a single wild pointer can wipe out your file system and a core dump means a reboot.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT or AMD-V. How do I install KVM under CentOS or Red Hat Enterprise Linux version 5.5?

A month and a half has passed since the release of Red Hat Enterprise Linux 5.5, but CentOS 5.5 has finally made it out into the world as the community equivalent to the RHEL5.5 packages.

Why does Red Hat tolerate CentOS?

Hundreds of new and improved drivers significantly improve hardware support in the 2.6.34 kernel

Some time ago Dell introduced the dynamic kernel module support (DKMS) to automatically recompile kernel modules during kernel updates. Now the first average-user apps supporting dkms emerged: VirtualBox and ATI graphics drivers.

When you buy a new PC, laptop or server and install a Linux you want to know what hardware is actually in the Linux box and more importantly which piece of hardware is supported by the kernel out of the box and which needs special tweaking with modules to get it work. Here is a list of commands which should help you to troubleshoot your hardware and find some information about it.
