Each Vmware guest you setup has a config file where you specify how much
memory to allocate to each VM. You also tell each VM what hardware to use,
only one OS..guest or host can use a piece of hardware, i.e. a serial port,
usb port. I have heard that you can attach a VM session to a cpu but I
haven't tried this.
