If you have a mixed network like I do sometimes you have to compromise. At my job we run Windows, Linux and a sole Mac (Graphics dept.) and lets face it, when you do consulting work and if you design and develop custom applications you have to be able to develop for your clients platform and as much as I hate it, it's a Windows world. Before I used to have 2 workstations, one Windows and one Linux, or I had to dual boot. In the past, virtual machines have been lacking. Either they were too slow or lacking a certain pizazz to get the job done. Enter
VMWare Workstation 4.
df is right. All you have to do is trap a few protected instructions and handle them.
Not sure how NT/XP does it, but I know on the old Win386 model, in fact, it was common for ring 3 code to *deliberately* cause a fault in order to get the VMM's attention.
Ah, life on the edge.
