Red Hat Enterprise Linux 5.4

In this section, we cover how to set up KVM VMs in a Red Hat Enterprise Linux 5.4 environment -- including setting up KVM hosts, creating KVM VMs and managing VMs in RHEL 5.4.

Red Hat has made headlines by natively supporting Kernel-based Virtual Machine (KVM) virtualization -- which makes Red Hat the first Linux provider to offer KVM as the default virtualization option. But while KVM virtualization technology is praised for its simplicity and power, it isn't widely deployed.

In this section of our open source guide to virtualization platforms, we cover how to set up KVM VMs in a Red Hat Enterprise Linux (RHEL) 5.4 environment, from start to finish -- including setting up KVM hosts, creating KVM VMs and managing VMs in RHEL 5.4.

How to configure Red Hat Enterprise Linux 5.4 as a KVM host
Before bringing VMs online in RHEL 5.4, you need to set up a RHEL server as a KVM host. Because native KVM support is new to this virtualization platform, many Linux virtualization users have questions about how RHEL and KVM work together. In this tip, we outline how to install KVM on a RHEL 5.4 server.

Creating KVM virtual machines in Red Hat Enterprise Linux 5.4
Once a RHEL 5.4 server is configured as a KVM host, it's time to create KVM virtual machines. All it takes is virt-manager and some patience. This tip eliminates the guesswork from creating KVM VMs in a RHEL environment.

Managing virtual machines in Red Hat Enterprise Linux 5.4
Both virt-manager and virsh, two virtual machine management tools for RHEL 5.4, have strengths and flaws. The virt-manager tool, for instance, has a easy-to-use graphical user interface but also limited functionality. Conversely, the command-line tool virsh can involve a steep learning curve but gives administrators full control over RHEL 5.4 VMs. This tip outlines the pros and cons of each VM management tool so that you can identify which one makes sense for your Linux virtualization environment and IT staff's skill sets.
