VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox. Initially developed by VMware for its proprietary [1] virtual appliance products, VMDK became an open format [2] with revision 5.0 in 2011, and is one of the disk ...
VMware VMFS (Virtual Machine File System) is VMware, Inc.'s clustered file system used by the company's flagship server virtualization suite, vSphere. It was developed to store virtual machine disk images, including snapshots. Multiple servers can read/write the same filesystem simultaneously while individual virtual machine files are locked.
[17] [19] [20] Other virtual machine software such as VMWare Workstation and VMware Player can mount raw floppy images in the same way. [21] Windows Virtual PC for Windows 7 (version 6.1) does not offer a user interface for manipulating virtual floppy disks; however, it still supports physical and virtual floppy disks via scripting. [22]
VMware Workstation supports bridging existing host network adapters and sharing physical disk drives and USB devices with a virtual machine. It can simulate disk drives; an ISO image file can be mounted as a virtual optical disc drive, and virtual hard disk drives are implemented as .vmdk files.
Freely-available tools from VMware (Disk Mount Utility) and LTR Data (ImDisk) can also be used to achieve similar functionality. Under Windows XP and Vista it is also possible to use the virtual hard disk feature by adding some component from Microsoft Virtual Server 2005 R2. [7]
libguestfs is a C library and a set of tools for accessing and modifying virtual disk images used in platform virtualization.The tools can be used for viewing and editing virtual machines (VMs) managed by libvirt and files inside VMs, scripting changes to VMs, creating VMs, and much else besides.

Virtual disk and virtual drive are software components that emulate an actual disk storage device.. Virtual disks and virtual drives are common components of virtual machines in hardware virtualization, but they are also widely used for various purposes unrelated to virtualization, such as for the creation of logical disks,software development, testing environments, and data management.
vCenter Server Appliance (VCSA) is the centralized management utility for VMware, and is used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location. VMware vMotion and svMotion require the use of vCenter and ESXi hosts.
