As was announced back in February, VMware is now giving away one of its flagship products, VMware Server (formerly GSX Server). The free OS virtualization server makes it possible to run multiple operating systems simultaneously on top of a host OS, which can eliminate dual-booting, make installing or testing potentially dangerous apps risk-free, or keeping around a copy of your old system when you reinstall Windows. VMware Server 1.0 is available for Windows or Linux.
