Set various attributes for your virtual machine, including messaging or terminal function keys: SLeep: Place your virtual machine in a dormant state indefinitely or for a specified period of time SMsg: Send a one-line special message to another virtual machine (usually used to control the operation of the virtual machine; commonly used with ...
Machine and software requirements are written in a file called "Vagrantfile" to execute necessary steps in order to create a development-ready box. "Box" is a format and an extension (.box) for Vagrant environments that is copied to another machine in order to replicate the same environment.

In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two.
Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. [4]One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world.
Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).

Thus, fetching the method's address from a given offset into a virtual method table will get the method corresponding to the object's actual class. [2] The C++ standards do not mandate exactly how dynamic dispatch must be implemented, but compilers generally use minor variations on the same basic model.
