A Horizon FLEX virtual machine is a software computer that, like a physical computer, runs an operating system and applications.

A Horizon FLEX virtual machine typically contains a display, a hard disk or disks, one or more processors, memory, a CD/DVD drive, a network adapter, and a USB controller. All of these components are virtualized. That is, these elements of a virtual machine are all created by software and stored in files on your computer.

Your Horizon FLEX virtual machine runs in a window on your local computer. You can install applications in the virtual machine and operate it as you would a physical computer. An operating system cannot distinguish between a virtual machine and a physical machine, nor can applications or other computers on a network. What you can do with a physical machine (install software, save files, add additional drives, and so on) you can do with a virtual machine.

Horizon FLEX virtual machines are fully supported by VMware Fusion® Pro and VMware Workstation Player™ with the underlying physical hardware. For example, you can use a virtual machine with virtual components that are completely different from the physical components that are present on the underlying hardware. Virtual machines on the same physical host can run different kinds of operating systems, including Windows and Linux.
