Assign the memory. It's in bytes, so calculate it accordingly (1 GB = 1,024 MB). Running Ubuntu you don't need a ton of memory, depending on what you are doing, but if you plan on running an IDE of some kind you'll want to at least provide some decent amount of RAM. My default is 6 GB/6,144 MB when I set up VMs. This will allow me to scale the memory up or down depending on my needs in the VM setup later.
