Features. Almost every Workstation feature is available on VirtualBox. This includes snapshots, thin provisioning of virtual disks, seamless windows, broad support for guest operating systems, and networking configuration. Whereas Workstation only can be installed on Windows and Linux hosts, VirtualBox host support also includes Mac OS X and Solaris operating systems.
While Workstation has linked-clone functionality, most Type 1 hypervisor users have more flexibility with snapshots and a larger number of guest operating systems.
