Oracle VM VirtualBox 5.2.0


Oracle VM VirtualBoxOracle VirtualBox是由德国InnoTek软件公司出品的虚拟机软件,现在则由甲骨文公司进行开发,是甲骨文公司xVM虚拟化平台技术的一部份。它提供用户在32位或64位的Windows、Solaris及Linux 操作系统上虚拟其它x86的操作系统。用户可以在VirtualBox上安装并且运行Solaris、Windows、DOS、Linux、OS/2 Warp、OpenBSD及FreeBSD等系统作为客户端操作系统。

与同性质的VMware及Virtual PC比较下,VirtualBox独到之处包括远程桌面协议(RDP)、iSCSI及USB的支持,VirtualBox在客户机操作系统上已可以支持USB 2.0的硬件设备,不过要安装 virtualbox extension pack.

Overhauled VM selector GUI (improved tools VM / global tools handling, new icons)
Added experimental audio support for video recording
In addition, the following items were fixed and/or added:

VMM: fixed reason for recent Linux kernels on also recent CPU models warning about “XSAVE consistency problem”
GUI: Virtual Media Manager rework allowing to manage media attributes, like size, location, type and description
GUI: Host-only Network Manager implemented to simplify managing corresponding networks and their attributes
GUI: Snapshot Pane rework allowing to manage snapshot attributes, like name and description; reworked snapshot details which looks more clear, corresponds to VM Details pane and reflects current VM state difference according to last snapshot taken
GUI: Audio settings extended with possibility to enable/disable audio input/output; corresponding changed were done to Audio and Video Capture settings pages; VM Devices menu and status-bar extended with corresponding actions and indicator as well
GUI: improvements with accessibility support
GUI: Fixed double mouse cursor when using mouse integration without Guest Additions, actually a Qt 5.6 bug fixed with QT 5.6.3 (Mac OS X hosts only; bug #15610)
Audio: implemented (optional) device enumeration support for audio backends
Audio: implemented support for host device callbacks (e.g. when adding or removing an audio device)
Audio: HDA emulation now uses asynchronous data processing in separate threads
Audio: implemented ability to enable or disable audio input / output on-the-fly
Storage: implemented support for CUE/BIN images as CD/DVD media including multiple tracks
Storage: implemented support for the controller memory buffer feature for NVMe
Storage: first milestone of the I/O stack redesign landed
E1000: Fix for Windows XP freeze when booting with unplugged cable
NAT network: do not skip some port forwarding setup when multiple VMs are active (Windows hosts only; bug #17041)
Serial: fixed extremely rare misbehavior on VM poweroff
EFI: better video mode handling, supporting custom video modes and easier configuration (bug #6783)
BIOS: properly report floppy logical sectors per track for unusual formats
BIOS: update ATA disk parameter table vectors only if there is actually a corresponding ATA disk attached
PXE: speed up booting by better handling pending packets when the link is not up yet
VBoxManage: handle CPUID sub-leaf overrides better
Windows Additions: fix several 3D related crashes
Solaris hosts: allow increasing MTU size for host-only adapter to 9706 bytes to support jumbo frames
Linux Additions: on systems using systemd, make sure that only the Guest Additions timesync service is active

    […]   新出的Windows 7里面有一个XPM技术,即Windows XP模式,是为了安装一些老软件而特意增加的新功能。但是你想要开启XP模拟模式,首先你的CPU必须要支持虚拟技术(简称:VT),向我们这种穷人所使用的赛扬、奔腾等等肯定是不支持的。不过没关系,有了VirtualBox,也可以让你梦想成真。 […]
