    en.wikipedia.org/wiki/VirtualBox

    Virtual machine cloning; 4.2 Sep 13, 2012: Virtual machine groups – allows management of a group of virtual machines as a single unit (power them on or off, take snapshots, etc.) Some VM settings can be altered during VM execution; Support up to 36 NICs in case of the ICH9 chipset; Support for limiting network I/O bandwidth

  3. System virtual machine - Wikipedia

    en.wikipedia.org/wiki/System_virtual_machine

    The desire to run multiple operating systems was the initial motivation for virtual machines, so as to allow time-sharing among several single-tasking operating systems. In some respects, a system virtual machine can be considered a generalization of the concept of virtual memory that historically preceded it.

  4. Virtual machine - Wikipedia

    en.wikipedia.org/wiki/Virtual_machine

    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.

  5. Hypervisor - Wikipedia

    en.wikipedia.org/wiki/Hypervisor

    A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .

  6. Hardware virtualization - Wikipedia

    en.wikipedia.org/wiki/Hardware_virtualization

    The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. [2] [3] Platform virtualization is performed on a given hardware platform by host software (a control program), which creates a simulated computer environment, a virtual machine (VM), for its guest software ...

  7. Virtual machine escape - Wikipedia

    en.wikipedia.org/wiki/Virtual_machine_escape

    In theory, a virtual machine is a "completely isolated guest operating system installation within a normal host operating system", [2] but this isn't always the case in practice. For example, in 2008, a vulnerability (CVE-2008-0923) in VMware discovered by Core Security Technologies made VM escape possible on VMware Workstation 6.0.2 and 5.5.4.

  8. Virtual machine introspection - Wikipedia

    en.wikipedia.org/wiki/Virtual_machine_introspection

    In computing, virtual machine introspection (VMI) is a technique "for monitoring the runtime state of a system-level virtual machine (VM)", which is helpful for debugging or forensic analysis. [1] [2] The term introspection in application to the virtual machines was introduced by Garfinkel and Rosenblum. [3]

  9. Kernel-based Virtual Machine - Wikipedia

    en.wikipedia.org/wiki/Kernel-based_Virtual_Machine

    Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [1] KVM requires a processor with hardware virtualization extensions, such as Intel VT ...
