A "bare metal" virtual machine monitor, correctly called a "hypervisor," directly controls the hardware without using device drivers from another operating system

Virtual machines (VMs) revolutionized the data center. With the ability to easily spin up a machine and even roll back to a working state, VMs bring a level of ease IT would never have enjoyed. Rolling back your VM is handled by way of snapshots.
File Formats for Virtual Machines Open Virtualization Format (OVF)
The OVF Specification provides a means of describing the properties of a virtual system. It is XML based and has generous allowances for extensibility (with corresponding tradeoffs in actual portability). Most commonly, an OVF file is used to describe a single virtual machine or virtual appliance. It can contain information about the format of a virtual disk image file as well as a description of the virtual hardware that should be emulated to run the OS or application contained on such a disk image.
Oracle VM VirtualBox can import and export virtual machines in the following formats:
Open Virtualization Format (OVF). This is the industry-standard format. See Section 1.14.1, “About the OVF Format”. Cloud service formats. Export to and import from cloud services such as Oracle Cloud Infrastructure is supported. See Section 1.15, “Integrating with Oracle Cloud Infrastructure”.1.14.1. About the OVF Format
OVF is a cross-platform standard supported by many virtualization products which enables the creation of ready-made virtual machines that can then be imported into a hypervisor such as Oracle VM VirtualBox. Oracle VM VirtualBox makes OVF import and export easy to do, using the VirtualBox Manager window or the command-line interface.
https://www.virtualbox.org/manual/UserManual.html#ovf
Using OVF enables packaging of virtual appliances. These are disk images, together with configuration settings that can be distributed easily. This way one can offer complete ready-to-use software packages, including OSes with applications, that need no configuration or installation except for importing into Oracle VM VirtualBox.

JavaScript needs to fly from its comfy nest, and learn to survive on its own, on equal terms with other languages and run-times. It’s time to grow up, kid.
-
If JavaScript were detached from the client and server platforms, the pressure of being a monoculture would be lifted — the next iteration of the JavaScript language or run-time would no longer have to please every developer in the world, but instead could focus on pleasing a much smaller audience of developers who love JavaScript and thrive with it, while enabling others to move to alternative languages or run-times.
-
Despite a growing variety of languages that compile to JavaScript, the language itself remains the dominant language in both client-side and server-side eco-systems for web development. The idea of replacing JavaScript with languages that compile to JavaScript, has been explored, and for whatever reasons, it hasn’t really liberated anyone from JavaScript.
-
We standardize on a finite subset of JS (such as asm.js) — and avoid the endless struggle through future iterations of the JavaScript language, competing super-sets and transpilers
asm.js and RPython sound similar (restrictive subsets)
-
agree to accept JavaScript for what it is, but start to think of it as a kind of VM for other languages

RPython is now also used to write non-Python language implementations such as Pixie.

VirtualBox is one example.
-
For example Wine software in Linux helps to run Windows application .
-
is Wine process virtual machine actually?
I think it is, yes.
Wine was given as an example of a process VM above.
