VMware Player

VMware Player is a virtualization software package from VMware, Inc.. VMware Player can run existing virtual appliances and create its own virtual machines (which require an operating system to be installed to be functional). It uses the same virtualization core as VMware Workstation, a similar program with more features, but not free of charge. VMware Player is available for personal non-commercial use, or for distribution or other use by written agreement. No support is provided by VMWare, but there is an active community website for discussing and resolving issues.
