The hardware requirements are:
A computer with at least 8GB of RAM. Preferrably, the RAM should be 12 GB or more.  This is required to setup a SQL Server virtualized environment.
If you don’t meet the hardware requirements, you can always install SQL Server on your host machine instead of the virtual machine.
