A pretty common misconception is that VMWare is based on Linux. That isn’t “officially” true. While there have been some rumors otherwise the official word from VMWare is that ESX (their bare-metal product) boots the system on a small “micro-kernel” they call the VMKernel. According to everything that I can find VMWare runs their OS off of their own manufactured product and use Linux to interact with or manage their product.
With ESXi they have stripped out large chunks of that the managing OS that is Linux and are working on beefing up their own OS. The idea is a good one but if you were to strip out all off the management of the product would you still have a product? One of the things that makes ESX great is it’s ability to be easily managed. If you take that away what are you left with?
So I would say that VMWare isn’t based on Linux … mostly.

EVC – The KB article on EVC (1003212) has been updated to be more comprehensive.
The KB article on EVC processor support has been updated with more information on the specific models of processors that are supported. You can find the info here.
Microsoft has changed their licensing so that they are more “friendly” to competing hypervisor products. This also extends to their support of their products on other hyper-v platforms which currently are Xen, VMWare and Novell’s virtualization product.
While they are supporting several additional virtualization platforms they are not extending this level of support to all of their products. For a complete list and the press release see the links below.

In the virtualization market there are a number of players. There is Citrix Xen Server, Microsoft Hyper-V and VMWare server on the bar-metal and OS virtualization side of things. But on there is also application virtualization of applications with Microsoft’s Soft-Grid and virtualization of desktops with VMWare’s VDI.
Wouldn’t it be nice if there was one place that you could go to discuss all of these technologies. Review the information in a website that wasn’t trying to sell you anything or support a particular bias. There is a new website just launched that endeavors to do just that. The website is very new so the information that it has right now will be sparse but the catalog of information that it will retain will soon be quite formidable.

Windows Vista has been out for over a year now. If an operating system is going to make any head-way in the IT industry it needs to happen soon after the release. While there is a slim chance the OS could a late bloomer that is pretty unlikely given it current state. So much so that people will buy Vista only to install XP after the fact (see link below). In a few recent articles Windows XP is still outselling Windows Vista.
Vista is one of those operating systems where people aren’t totally sure where they want to fall or what side they want to be on. On the one hand I truly believe that people are ready for and want a new operating system but on the other hand they see too many people and companies who have been burned by the Windows Vista OS. Most people are still in the wait-and-see state which isn’t good for this OS because it is ends up giving it a bad name. What have you found in your workplace?

Vista to XP Downgrade Report
How does the performance of Microsoft’s Hyper-V technology stand up against some of the more entrenched companies? Well, a not-so-scientific study was done recently to answer this very question. While I admit that this isn’t a “study” the results are interesting.
The fact that Windows Vista’s security has been by-passed isn’t new it bears repeating enough to make sure that everyone has heard this. Basically the security in Windows’s Vista and Windows Server 2008 that was supposed to make the new operating system more secure than any previous operating systems from Microsoft hasn’t helped them. At the Black Hat conference that is going on two guys, one from IBM and one from VMWare, found a way to
It seems that their attempts have only made the situation worse, since from what I can tell, the vulnerability is easy to create, hard to stop and could become a plague overnight. Here are some links to help you sort out the topic for yourself.

Off-line files/folders is nice but it doesn’t work when you are on the road. iFolder is an open source product developed initially by Novell. It gives you a folder that will do block level synchronization over the Internet. You can check out iFolder here.
There are several remote access applications out there. LogMeIn is one that has been around of a while but is worth looking at nonetheless.
