Alessandro Perilli:Tracking the virtualization industry for more than six years (virtualization.info was launched in September 2003) has been a challenging, time-consuming and sometimes tiring task. But there always are fun moments.The best ones come from the never ending skirmish between VMware and Microsoft marketing departments (and their allies), that in turn highlight the negative aspects of the competitor.The VMware solution is too expensive and doesn’t manage anything but the virtual infrastructure, says Microsoft.The Microsoft solution is not mature enough, it’s full of bugs (because it comes from Windows) and has hidden costs too, says VMware....
The ability to assign more memory to virtual machines than physically available on a host is called memory overcommit and is a major factor that contributes to higher VM density — running more virtual machines per host increases efficiency and reduces cost. VMware ESX has provided this feature for multiple generations, giving it an advantage over competing hypervisors....

The Author is Elias Khnaser, this is his website and this is the company he works for. A few people have taken him to task over it, including Aidan .

When VMware introduced commodity server virtualization back in 1999, Microsoft hardly batted an eye. So what’s happened to make Microsoft not only care, but care enough to invest millions of dollars into their own server virtualization solution?It’s all about control....
