Why cant you use all of your systems memory to run a virtual machine?
You can't use all of your system memory to run a virtual machine because then there wouldn't be enough memory for the Operating System that's running the virtual machine to function. For instance, if you have 4 GB of system memory total, and your operating system needs at least a quarter of that (1 GB) to function, then your virtual machine maximum memory would be 3 GB.
