Virtual disk — A virtual disk is a file or set of files that appears as a physical disk drive
to a guest operating system. These files can be on the host machine or on a remote
file system. When you configure a virtual machine with a virtual disk, you can install a
new operating system into the disk file without needing to repartition a physical disk
or reboot the host. Virtual disks can be preallocated or growable. A preallocated virtual
disk has all the disk space allocated at the time the virtual disk is created. A growable
disk is not preallocated; its files start out small in size and grow as data is written to it.

Virtual machine configuration — The specification of what virtual devices (disks,
memory size, and so forth) are present in a virtual machine and how they are mapped
to host files and devices.
Virtual machine configuration file — A file containing a virtual machine
