From Wikipedia, the free encyclopedia
- VirtualBox is open-source software for virtualizing the *86 computing architecture.
- It acts as a hypervisor, creating a VM (virtual machine) where the user can Run another OS(Operating system).
- The operating System where VirtualBox runs is called "Host" OS.
- The operating system running in the VM is called the "Guest" OS.
- VirtualBox supports Windows, Linux or macOS as its Host OS.
- When configuring a Virtual machine, the user can specify how many CPU cores and how much Ram an Disk Space should be devoted to the VM.
- When the VM is running, it can be "paused".
- System execution is frozen at that moment in time, and user n reusing it later.
