Comments on Virtualization With KVM On A CentOS 6.2 Server

Virtualization With KVM On A CentOS 6.2 Server This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 6.2 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. Intel VT or AMD-V.

Why is it that many tutorials always start out to the effect of, "First, disable SELinux.  I don't know if it works with SELinux, but to avoid problems..."

As you're doing the technical work to prepare a tutorial, you should always leave SELinux enabled... if, and only if, you encounter a problem that would take you a long time to work through, then you disable SELinux.

I just installed C6.2 on a laptop, and I've installed a handful of KVM virtual machines through the GUI interface.  Not once did I have to tweak SELinux, and not once did I get an error related to SELinux disagreements with KVM.  The management tools - at least the GUI based tools - should handle that for you.
