Know the usage to understand if it is virtual machine or a physical machine.
Installing Server 2008 in a virtual machine is really no different than installing in a physical box; you boot the install DVD in the virtual machine and follow the prompts the same way as booting from the DVD on a real, physical machine.
Not on a physical system. If you run one in a virtual machine on top of the other, then yes.
By installing the network drivers provided by the virtual machine.
That's the "base" operating system. Let's say you have Windows 7, and you need Windows XP for compatibility (for instance, lots of older games no longer work with Windows 7). So you install a virtual machine using a special program such as as VMWare, and you run Windows XP in a window within Windows 7. (It can be full-screen as well.) Or perhaps you want to try out Linux. In this example, the base machine - the real, physical machine - has Windows 7; that's the host operating system, while the virtual machine has Windows XP (or Linux).Note: It is also possible, for example, for the host operating system to be Windows 7, and the virtual machine also Windows 7 - this can help you isolate different installations, and - for example - if you no longer need it, erase the entire virtual machine, which is faster, and often much cleaner, than uninstalling.
Virtual machine
Use Windows Virtual Machine or VMWare.
Use Microsoft Virtual PC, install a pre-made Windows 98 virtual machine, and then install Riven on the virtual machine. See http://digiex.net/applications/1022-digiex-exclusive-premade-windows-98-virtual-machine-use-older-games.html for links to MS Virtual PC and the pre-made Win98. Installation is easy, and it works flawlessly.
You only choice is limited to virtual machines such as VMWare. And of course you will have to install MAC OS on your virtual machine.
No. That's what "virtual" means.
You can't. You could run it on a Linux virtual machine inside windows though.
A virtual server is one that creates partitions within a physical server so that it functions as several servers, virtually. A Windows Virtual Server is one that runs on the Windows Operating System.
