You could wonder if VMWARE Fusion 4 is the work of the devil. Or perhaps it’s the snake from the Garden of Eden. Or in the ultimate irony and twist of fate, perhaps VMWARE Fusion 4 is the apple from the Garden of Eden, offered by Eve to Adam, which was responsible for the downfall of Mankind.
That’s exactly what VMWARE Fusion 4 seems to be. It’s a temptation. Fusion 4 from VMWARE allows Mac OS X users the capability to run a Windows operating system on a Macintosh. Or worse, it allows the wholesale migration of an entire existing Windows machine into the Mac. Why would anyone want to do that?
I and other true-blue Mac users know that a Windows operating system should never be installed on a Mac. To install Windows on a Mac would be like seeing a velvet Elvis hanging in the Louvre Museum in Paris. It simply is not done. And you don’t have to explain this to people who understand. You don’t have to convince anyone at the Louvre why a velvet Elvis should not be there just as you don’t need to explain to true Mac users why Windows should never be co-mingled with the Mac.
We all understand why. Steve Jobs said it best
The only problem with Microsoft is that they just have no taste. They have absolutely no taste and what that means is – and I don’t mean that in a small way, I mean that in a big way – in the sense that they don’t think of original ideas and they don’t bring much culture into their product… Why is that important? Proportionately spaced fonts comes from typesetting and beautiful books – that’s where one gets the idea. If it weren’t for the Mac they [Microsoft] would never have that. I am saddened not by Microsoft’s success – I have no problem with their success; they have earned their success for the most part. I have a problem with the fact they make really third-rate products. – Steve Jobs
This is why I have avoided Mac Boot Camp. Boot Camp provides the capability to install Windows in a partition on a Mac computer. It’s probably the case the Steve Jobs, a good business person, reluctantly agreed to building this capability into a Mac. Perhaps this provided an opportunity to win more Mac users if Apple offered a machine that could run both the Mac and Windows operating systems. So, Boot Camp may be Apple’s offering of redemption in the post apocalyptic Garden of Eden that we now live in where the majority of personal computers are based on Microsoft Windows.
A moment of weakness
In a moment of weakness I decided to see what the snake was offering. You can get a 30 day trial of VMWARE Fusion 4 from the VMWARE website.
If you work in a large corporate environment that real PC desktop on your desk might soon turn into a virtualized desktop on a corporate virtualized environment. Same with that application server. Virtualization is now a mature technology. If you have Windows 7, you already have the ability to run a virtualized Windows XP alongside Windows 7. And this is just the start.
If you are on the techie side, and want to find out about virtualization in general and two competing solutions in particular then take a look at his white paper.
The battle to be your virtualization vendor is in full swing, and it has important ramifications for the vendors involved, and for your data center. The goal of this whitepaper is to analyze the technical aspects of the two major choices: VMware vSphere 4 and Microsoft Hyper-V R2 (as part of Windows Server 2008 R2). This paper considers server virtualization alone, not desktop virtualization or “presentation virtualization”. Certainly presentation virtualization will be an important aspect of the virtualization gamut, but with the entry of Microsoft into the server virtualization market, and the still-unrealized huge potential for server virtualization, this is a topic of great interest to many datacenters.

Check out our previous postings on the subject of virtualization
It’s the great chain of related content. First we suggested that you use Clonezilla to do disaster recovery on your Linux System. Then we suggested that you don’t need that – that you should go Virtual instead. Would you ever trust us or are we just giving you the run around on what do to about your pesky Linux system?
Regarding Linux disaster recovery what problem are we trying to solve? We are trying to solve a problem that, really, needs to be solved because we may have made an error in judgement. Or, simply, that we don’t understand things clearly. What have we not understood – what is the essence of the question that will inform our judgement?
Lets think about this. We have confused value with hardware. You need to ask yourself a critical question. Is Linux about Linux or is Linux about creating value?
If you answer that Linux is about value – then the hardware and the operating system is a nuisance – you need to make it go away. Really, you need to transfer the nuisance and the problem to someone else.
Computing in the Cloud
So, now the ultimate solution to your disaster recovery backups and the pesky physical hardware that sits there running Linux – contemplating in-itself when it will surprise you with a disk or other hardware failure – is to think in a new way about why you would want to own any hardware at all.
Another virtualization solution with pre-built guest operating systems. This is a free solution from Sun Microsystems. We were able to try this virtualization product with pre-built guest operating systems Ubuntu 8, Fedora 10, and CentOS. This is a very excellent solution which will compete with Microsoft Virtual PC 2007. The large number of pre-built virtual disks of configured operating systemsmake this virtualization soltion a real winner – http://virtualbox.wordpress.com/
There is a term/concept you might hear related to PC’s and operating system. The term you might hear is “bare metal”. Bare metal as in installing an operating system on ‘bare metal”. What does this mean?
This term, bare metal, is only possible because of another term – virtualization. You might hear the term “guest operating system”. A guest operating system runs on a platform that supports virtualization.
So what is virtualization? In simple terms it means that you have some software that is capable of emulating the hardware of a PC to the point that you can install on operating system on it and have it run as if it was on bare metal.
So, if you put this all together, bare metal is the real hardware. Virtualization is the capability to emulate PC hardware in software to the point that you can install an operating system and have it work as if it was bare metal. The installed operating system in the virtualized environment becomes the guest operating system. The guest operating system run’s in a virtual machine in the virtualized environment
The really cool thing, is that if you have a nice big server with lots of CPU, memory, disk, and other hardware resources plus reliable software that can create the virtualized environment you can run a lot of guest operating systems on a single server.
Here is a more concise definition of virtualization:
DSL – Damn Small Linux
By now you have probably heard about Linux. Maybe you wanted to try it out and see what it was all about. Then you found out that to install Linux you had to create a new partition on your hard disk, or buy a new hard disk, make a dual boot system, or otherwise disturb your beautiful MS Windows operating system. Then, if you got it installed how would you get if off your system when you were done playing with it? How would you get rid of the dual boot software – grub or lilo – and get the Microsoft boot blocks back on your hard disk?
Well heck, where there is a will there is a way.
