VirtualBox 开源虚拟机软件
VirtualBox 是一款开源虚拟机软件。VirtualBox 是由德国 Innotek 公司开发，由Sun Microsystems公司Sun Microsystems公司出品的软件，使用Qt编写，在 Sun 被 Oracle 收购后正式更名成 Oracle VM VirtualBox。Innotek 以 GNU General Public License (GPL) 释出 VirtualBox，并提供二进制版本及 OSE 版本的代码。使用者可以在VirtualBox上安装并且执行Solaris、Windows、DOS、Linux、OS/2 Warp、BSD等系统作为客户端操作系统。
VirtualBox 5.1.0 版本发布，这是一个重要的更新，主要是在性能的提高和多媒体的支持上。
更新日志：
VMM: new APIC and I/O APIC implementations that result in significantly improved performance in certain situations (for example with networking, bug #15295)
VMM: added support for Hyper-V paravirtualized debugging of Windows guests
VMM: emulate even more MMIO and shadow pagetable exits without going back to user mode
GUI: overall migration to Qt5 (bug #11775)
GUI: passive API event listener improving the VM GUI performance and response time
Audio: added HDA (High Definition Audio) support for newer Linux guests
Audio: added on-demand timers which should improve the overall performance and reduce the CPU consumption
Audio: more fine-grained volume control for the AC'97 emulation, which now also takes the master volume control into account
better support for Python 3
添加/修复了以下项目：
VMM: activate the x2APIC by default for Linux guests
VMM: many more fixes
GUI: the Detach UI action is now a part of the VM Machine menu

Storage: use fallocate() or similar if present to speed up creating fixed-sized disk images (bug #5967)
Storage: implemented NVMHCI-compatible storage controller
Audio: various bugfixes and infrastructure improvements
E1000: implemented interrupt throttling for performance improvements
EFI: many improvements, for example allow to boot from USB
OVF: improved handling of signed manifests

VBoxSVC: fixed several memory leaks when handling .dmg images
Installers: ship VBoxBugReport
Windows hosts: reworked COM proxy (e.g. bug #8298)
Linux installers: no longer rely on DKMS for module rebuilding
