VMware Unity mode is a feature in VMware desktop virtualization products that allows a user to display applications from virtual machines (VMs) on the host system desktop. Unity mode provides access the Start and Applications menus from the host system while the VM's console view is hidden. Unity mode requires Linux or Windows 2000 or later guest operating systems.
When saving or opening a file in Unity mode, it must be from the VM. Users are unable to save or open files from the host operating system. However, users are able to drag and drop and copy and paste files between the host system and the guest operating system.
Unity mode can be displayed on additional monitors if the host and guest operating system are both either Windows XP or later, but application windows will only display on one monitor for other operating systems. Unity mode is not available in full-screen mode in Windows and can't be used with remote VMs.
