Again, only if the hosted linux was running on x86 (or what looked like
x86). VMWare is not an x86 emulator, it is a virtual machine emulator.
It will only run on x86 hardware as most of what it does is pass the
instructions right on through to the processor, only trapping a few
specific things. (this is why it can seem so fast) Now you could run NT
from within bochs on a hosted Linux OS, because it _is_ an x86 machine
emulator.
