- First, I am very glad you are starting to pay attention to the
- arguments, and even refer back to some, instead trying to prove me
- wrong. Second, you are beginning to get the picture. Third, this
- particular argument you are commenting is exsplicitly (sp?) to explain to
- you that although virtualization contains control,
- virtualization!=control. Fourth, I have finally poin-pointed some
- concepts you confuse, and therefore, I have writting out the email
- about the VM operating system, and the virtual machine concept, in
- which you should particularaly pay attention that in layered operating
- systems the top operating system does not penetrate into the lower
- operating system-- it is not even our of it's existence, it views
- everything underneath it as a bare-machine. The last statement may be
- released to you a little bit pre-maturely, you have first to realize
- that your argument should be that windows is an operating system
- layered over DOS.
