Virtualization Made Easy In Ubuntu 8.04

Filed under
Ubuntu

One of the features that was introduced a year ago into Ubuntu 7.04 "Feisty Fawn" was support for KVM, which is the Kernel-based Virtual Machine. The Kernel-based Virtual Machine provides full virtualization support for Linux when running on x86 hardware with either Intel's VT or AMD-V technology, which means you can run unmodified guest operating systems such as Linux or Microsoft Windows within your Linux host operating system.

As we had shared in benchmarks, KVM -- even back to its infancy -- has been quite fast at virtualization when compared to Xen or kqemu. However, the KVM virtualization support found in Ubuntu hasn't been the most user-friendly. Installing and then managing these guest operating systems in Ubuntu 7.04 and Ubuntu 7.10 has required using the command-line interface and thus requiring the user to be familiar with the various QEMU options. However, in Ubuntu 8.04 this has all changed for the better now that virt-manager and libvirt are available from the main Ubuntu repository.

KVM support had premiered in Fedora 7 "Moonshine" around the same time as Ubuntu 7.04, but this virtualization support was accompanied by two new Red Hat innovations: virt-manager and libvirt. Virt-manager is the Virtual Machine Manager and is a GUI for managing virtual machines while at its foundation is libvirt, which is a virtualization API for not only interfacing with KVM but also Xen, QEMU, and OpenVZ. Virt-manager goes beyond just providing a user interface for facilitating the installation and basic management of the guest operating systems, but also provides a detailed analysis of the guest performance/resource usage and modifying the virtual system details (CPU cores, disk size, network devices, and memory capacity).

OpenMediaVault 1.0, a Complete Free NAS Solution You Didn't Know You Needed

As you can expect, there are a ton of free NAS (network attached storage) projects and solutions on Linux (and beyond), but there is always room for one more. OpenMediaVault packs quite a few features and users will most likely find all the options that they will ever need. The OpenMediaVault might have a round and neat version number, but the project has been around for a few years now and it's made by Volker Theile, a former member of FreeNAS, which is another very famous NAS solution.
