VirtualBox emulates hard disks in three formats: the native VDI (Virtual Disk Image), [36] VMware's VMDK, and Microsoft's VHD. It thus supports disks created by other hypervisor software. VirtualBox can also connect to iSCSI targets and to raw partitions on the host, using
This type of VM has become popular with the Java programming language, which is implemented using the Java virtual machine. Other examples include the Parrot virtual machine and the .NET Framework, which runs on a VM called the Common Language Runtime. All of them can serve as an abstraction layer for any computer language. [citation needed]
Built-in vRDP support in VirtualBox can be used to remotely access operating systems that lack a built-in RDP server, such as Linux. In 2013, Oracle announced that it was discontinuing all further development of Oracle VDI, although existing customers would continue to be supported for a transitional period. [1]
With the VM architecture, most users run a relatively simple interactive computing single-user operating system, CMS, as a "guest" on top of the VM control program . This approach kept the CMS design simple, as if it were running alone; the control program quietly provides multitasking and resource management services "behind the scenes".
^ Exceptional for lightweight, paravirtualized, single-user VM/CMS interactive shell: largest customers run several thousand users on even single prior models. For multiprogramming OSes like Linux on IBM Z and z/OS that make heavy use of native supervisor state instructions, performance will vary depending on nature of workload but is near native.
One form of desktop virtualization, virtual desktop infrastructure (VDI), can be thought of as a more advanced form of hardware virtualization. Rather than interacting with a host computer directly via a keyboard, mouse, and monitor, the user interacts with the host computer using another desktop computer or a mobile device by means of a ...
Managed VDI, which is based on VDI technology provided as an outsourced managed service, and; Desktop as a service (DaaS), which provides a higher level of automation and real multi-tenancy, reducing the cost of the technology. The DaaS provider typically takes full responsibility for hosting and maintaining the computer, storage, and access ...
