I have not upgraded to the latest VMWare Workstation -- should I take a look at QEMU first or is this something meant for a completely different use case? (I use VMWare Workstation for contracting/consulting and build out a workstation to match the client engagement rather than pollute my base OS with five different versions of Visual Studio; IntilliJ, Eclipse, AND Android Studio; multiple version of SQL Server/PostgreSQL/Mongo/MySQL... and I can dump those VMs off to network storage when I'm done with the engagement and reclaim the storage space on my laptop.)
