VMware Server

VMware Server (formerly VMware GSX Server) is a discontinued free-of-charge virtualization-software server suite developed and supplied by VMware, Inc.

VMware Server has fewer features than VMware ESX, software available for purchase, but can create, edit, and play virtual machines. It uses a client–server model, allowing remote access to virtual machines, at the cost of some graphical performance (and 3D support). It can run virtual machines created by other VMware products and by Microsoft Virtual PC.
