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.

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.
Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system. In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.
Reverting to a snapshot failed following a specific set of steps. A Windows 10 guest operating system running idly caused Workstation to crash. Using the Easy Install option to install the Ubuntu 14.04 or Ubuntu 15.04 guest operating system failed to install VMware Tools. 12.0.0 Pro [51] 24 August 2015
The Guest Additions for Windows, Linux, Solaris, OpenSolaris, and OS/2 guests include a special video-driver that increases video performance and includes additional features, such as automatically adjusting the guest resolution when resizing the VM window [38] and desktop composition via virtualized WDDM drivers.
Proxmox VE supports live migration for guest machines between nodes in the scope of a single cluster, which allows smooth migration without interrupting their services. [18] Since PVE 7.3 there is an experimental feature for migration between unrelated nodes in different clusters. [19]
Then, the copy, called the "child process", calls the exec system call to overlay itself with the other program: it ceases execution of its former program in favor of the other. The fork operation creates a separate address space for the child. The child process has an exact copy of all the memory segments of the parent process.
Disadvantages are that sparse files may become fragmented; file system free space reports may be misleading; filling up file systems containing sparse files can have unexpected effects (such as disk-full or quota-exceeded errors when merely overwriting an existing portion of a file that happened to have been sparse); and copying a sparse file with a program that does not explicitly support ...
