Before we move on to the next step, there are a few things you’ll want to keep in mind when using a VM.
A VM will never be more powerful than the computer on which it is running. Both the Linux OS and the VM OS will be sharing resources. In fact, it will always only be a portion of the full power of your computer. You will allocate resources when you set up Windows in the VM, such as how much shared RAM or how much hard drive space to use.
Memory and Hard Drive
For example, if you have 8 GB of memory on your computer, you might set 4 GB to use on the VM. While the VM is running, it will use 4 GB of memory and the host computer will only have 4 GB of memory. When the VM is shut off, the host computer will get the full 8 GB back.
Hard drive space allocation is different. Once hard drive space is set for the VM, that disk space will always be reserved for the VM, even when it is not running. For example, if you have a 500-GB hard drive and allocate 120 GB for the VM, your physical computer will make 380 GB available for Linux and 120 for the VM.
It’s important to note the system requirements to run AutoCAD need to be met within the VM. Because you will be sharing resources, your physical machine must have much higher specs than what is required for AutoCAD alone. Your physical machine will need to support Linux, the virtual install of Windows, and AutoCAD. Whew, that’s a lot!
With a 64-bit Windows 7 OS, AutoCAD requires a 1 GHZ of CPU speed, 4 GB of memory (8 GB recommended) and 4 GB of hard disk space for installation. Therefore, you will need to set up your VM with these parameters as a minimum.
