Changelog

This is a maintenance release. The following items were fixed and/or added:

    GUI: Mac OS X: Restore green zoom button for VM windows (it was hidden in the previous release to avoid native full-screen issues). For Yosemite and El Capitan this button should work accordingly to the Apple HIG: Full-screen by default, maximize if the user holds the Option key.

    API: fixed a 5.0 regression in VBoxManage setproperty defaultfrontend (bug #14696)
    VBoxManage/vbox-img: conversion to RAW images could result in a disk image containing all zeroes
    Linux hosts: several fixes for systemd integration in .deb / .rpm packages (e.g. bug #14665). The command for recompiling the host kernel modules was changed to /sbin/vboxconfig
    Linux hosts: make host-only interfaces report operstate UP only when they have VMs attached (bug #14526)
    Mac OS X hosts: fix bpf capture and accounting of traffic on bridged and host-only interfaces (bug #14553)

Release Notes

Latest release provides improved multimedia support, increased Linux integration and new bug reporting helper tool.

To enable organizations and developers to more easily and flexibly create and deploy on premises and cloud applications, we are pleased to announce the general availability of Oracle VM VirtualBox 5.1, the latest release of the world’s most popular free and open source, cross-platform virtualization software.

A key tool for developers and users creating cloud and local applications without the overhead of using a full server environment, Oracle VM VirtualBox runs on standard x86 desktop and laptop computers. It allows users to set up multi-platform virtual machine environments for software development, testing, and general purpose operating system (OS) virtualization, with optional runtime encryption. Software engineers can develop for cloud technologies such as Docker and OpenStack from within Oracle VM VirtualBox VMs directly on their Windows, Mac OS, Oracle Linux and other Linux operating systems, and Oracle Solaris machines, making it easier to create multi-tier applications with just a standard laptop. Oracle VM VirtualBox also enables users to create and update virtual machines locally, including the OS and applications, and then package them into an industry standard file format for easy distribution and cloud deployment in conjunction with Oracle VM Server, or other server virtualization solutions. Oracle VM VirtualBox allows users to run nearly any standard x86 OS to run applications that are not available natively on their systems.

With thousands of downloads for each day, Oracle VM VirtualBox 5.1 continues to remain the best virtualization solution available for standard desktop and laptop computers and, at the same time, addresses the challenges to enable the use of a wide range of virtual machine environments and operating system with emulation of latest technologies available, improved performance and increased integration.

The 5.1 release supports the latest guest or host operating systems including: Mac OS X Yosemite, Windows 10, Oracle Linux, Oracle Solaris, other Linux operating systems, and legacy operating systems. New main capabilities in Oracle VM VirtualBox 5.1 are:

    Improved Performance: Significantly improved performance for multi-CPU virtual machines and networking.
    Bug Reporting Tool: New utility able to collect all the information and logs related to the host and guest operating system, for debug or analysis purposes.
    Improved Logging Window: New logging functionalities to highlight and filter information related to guest Virtual Machines.
    Improved multimedia availability: Improved support for different USB devices and multi-channel audio availability.
    Flash storage emulation: New NVMHCI storage controller emulation available, able to emulate NVME devices - Flash storage - on guest Virtual Machine.
    Improved Linux integration: Automatic modules deployment in case of a Linux Kernel upgrade and improved systemd integration for the latest releases of popular Linux distributions.
