Virtual machines are virtually taking over the world. By itself a virtual machine is just a container that describes various resources such as memory, disk space, processor, and network card, and allocates them from a physical machine. As with a physical machine, it's the software bits (the operating system and applications) that make a virtual machine usable.
You’ve been seeing a lot of virtualization specific posts recently here at Ubuntu Tutorials. I’ve been tinkering with a number of virtualization options, namely VMware Server, Virtualbox and now KVM with Virt-Manager.
Virtualbox 1.6, which was released in May 2, was the first major release since Sun took over virtualbox. All I can say is Wow!! This is perhaps the single biggest, most important open source release which will change the face of how computers are used for years to come. Hell this is even bigger than the release of hardy heron (IMO), and Ubuntu 8.04 LTS was a very important release.
Sun xVM VirtualBox software is the world's most popular open source virtualization platform because of its fast performance, ease of use, rich functionality, and modular design.
VirtualBox 1.6 is a major update, incorporating over 2000 improvements. Among the highlights:
* The new Sun livery
* Solaris and Mac versions no longer in beta
* Guest Additions for Solaris
* Seamless windowing for Solaris and Linux guests
* SATA support for up to 32 hard disks per VM (first product in the industry to do SATA!)
* PAE support for guests (memory model required by some server OSes)
* Web Services API for remote management
* Significant improvements to scalability
With all the Linux distributions available, trying out more than one can be tempting. By installing a virtual environment, you can run several operating systems on your machine, keeping them completely isolated from each other in their own sandboxes. Here's a look at how get started with three popular virtualization environments: VMware, VirtualBox, and QEMU.
Commercial Debian Linux distributor Canonical has given its moniker to the next iteration of its Ubuntu Linux, code-named "Intrepid Ibex" in keeping with the silly names the Ubuntu project uses and probably coming to market as Ubuntu 8.10 in October. The company has also talked a bit more about the Ubuntu 8.10 feature set, its use of KVM virtualization, and a reseller deal it has with IBM to peddle the DB2 Express-C development database.
The next major production release of Ubuntu — version 8.04 LTS, codenamed Hardy Heron — will ship with KVM as its virtualization package. This choice is surprising to those of us who have been watching the Xen virtualization package become the darling of Virtual Machine world. So let’s try to make sense out of the KVM virtual machine and this recent choice by Ubuntu.
LONDON, February 7, 2008 - Canonical Ltd, the commercial sponsor of Ubuntu, today announced the availability of Parallels Workstation for Linux through the Ubuntu Partner Repository – giving Ubuntu users the ability to quickly find, install and run Parallels software.
Virtualization is the technique of running a "guest" operating system inside an already-running OS; for example, Windows inside Linux, or visa-versa. This week Canonical, the company behind Ubuntu Linux, announced a partnership with Parallels, maker of the Virtualization products Parallels Workstation and Parallels Desktop for Mac. This article compares four virtualization products available for Ubuntu Linux: the free, open source Qemu; the closed-but-free versions of VirtualBox and VMware-Server, and the newly-available, commercial Parallels.
Have you ever wanted to actually try Ubuntu Linux (Live CD’s don’t count) without having to worry about partitioning or installing another hard drive or setting up a dual boot? This step by step guide will walk you through the exact steps to run Ubuntu totally inside of Windows utilizing a virtual machine.
One of the hottest new technologies for servers is virtualization, which allows you to install multiple instances of one or more operating systems on one machine. This is ideal especially for servers with a low average load because, instead of configuring a separate physical box for every single instance of an operating system you need, you just run multiple instances of one or more operating systems on one machine.
VirtualBox is a piece of software that uses virtualisation to simulate a PC. With it you can run Windows, Open BSD or even Linux from your Debian system. Since it also runs on Windows and Mac OS, you can use it to run Debian from that other non-free OS. Note however that it only works on x86 and x86_64 hosts.
My previous tutorial on installing VMware Server on Ubuntu 7.10 has been wildly successful but I also realize now that it has become a bit out of date. This tutorial is an update with a few simplified steps. It will be nice when VMware Server makes it into canonicals partner repository (as is available on Ubuntu 7.04), but until then these few steps should work for most of us.
Early testing has shown that Ubuntu, when run as a virtual guest taking advantage of the new paravirt-ops paravirtualization interface, delivers as promised: it runs faster and more efficiently that it would as an unmodified guest. Ubuntu, a Linux distribution maintained by corporate sponsor Canonical Ltd., is the first commercially shipping operating system to support the paravirt_ops standard.
As I've mentioned in previous articles I currently have all the applications I need on my Ubuntu Linux desktop so I never need to use Windows. However, there are unfortunately still plenty of applications that some users need which are not available under Linux and have no equivalent. Adobe's Flash and Photoshop spring to mind, Turbotax is another that some miss, how about iTunes? Luckily for those users there are at least three options that will allow them to run the software they need while retaining Linux on their desktop. But which is the best one?
If you're like most people, you probably named VMware or Xen first. Many of you probably know of one or more of the following: Parallels, QEMU, KVM, Virtuozzo and OpenVZ. However, few of you probably know about VirtualBox. And chances are if you know about VirtualBox 1.502, you're already running it because it manages the trifecta of being good, free and, sort of, open source.
Canonical announced their release of Ubuntu JeOS (Just Enough Operating System, pronounced "juice") for VMware last week in San Francisco at the WMworld conference. This version will be a more compact and higher performance base for virtual machine "appliances" that bundle the operating system with higher level software.
Until now, Parallels has had problems compiling the the newest ubuntu kernels and now is working absolutely great on my ubuntu machine, i just ditched qemu, virtualbox, and vmware! Dont ditch yours just yet untill you have a feel of this Virtualization Solution that has suprised the hell out of me.
So far I have tried Windows XP, and PC-BSD and they both run much smoother on my box, it has new technology that takes full advantage of your hardware.
Here are some features..and a direct download :)
VirtualBox is open source virtualization software similar to VMware. I wanted to run a virtual Ubuntu LAMP server for testing, but I ran into a problem with VirtualBox.
