这是半年多前,甲骨文公司发布 Oracle VM的VirtualBox的3.2 ,以前被称为太阳的VirtualBox的更新,因为他们最近的专业。 甲骨文然而,现在正在准备一个非常重要的VirtualBox 4.0虚拟机更新。 今天,他们已发布了虚拟机VirtualBox的第一个公开测试版4.0 Oracle和它带来的开源社区的许多新功能,以及一些改变而甲骨文的开放的疏远,可能被证明是另一个令人失望。

之前,甚至一提的VirtualBox 4.0 Beta 1中的新功能,甲骨文公司的弗兰克Mehnert提到,一些功能被搬出来“外部包”,而不是作为核心的VirtualBox虚拟化软件的一部分。 现在这里只有一个外部的VirtualBox 4.0包和它的PUEL extpack,这就是在USB 2.0,RDP服务器,支持和PXE引导程序驻留。

没有什么是对这些目标的VirtualBox 4.0外部包说,但它可能是一个有点在寻找的VirtualBox作为一个自由和开放源码的虚拟化堆栈的烦恼。 甲骨文可能开始出售这些“外部包”的用户提供核心,但不一定需要虚拟化客户机操作系统的功能。 支持USB 2.0在VirtualBox客户机是漂亮的桌面用户,是有点让人吃惊,他们将进入这些外部包一出的核心功能。

除了销售VirtualBox的外部包,甲骨文也可以使用这样的一种方式“功能”,以提供更多的功能,但只能通过封闭源代码的外部包。 这虽然只是我的假设,但甲骨文公司在如何处理其他“开放式”项目,他们通过收购Sun收到,这样做肯定是有可能的。 我们只能等待,看看会发生什么,但。

总 之,在为VirtualBox的4.0的新功能方面,改进包括新设置/磁盘文件为虚拟机的可移植性,卵子布局(开放虚拟化格式的包)的支持,Java语言 的绑定,支持作为一个虚拟化的选择ICH9芯片组,英特尔高清晰度音频作为虚拟客户端音频可用,有一个与客人的窗口预览,作为一个按比例缩小客人展示新的 显示模式,限制了同步我的虚拟机的CPU时间和I / O带宽,支持支持重新设计的用户界面/ Ø在iSCSI /的VMDK / VHD的/ Parallels的图像,改变大小的VDI / VHD的图像的支持。 这些只是最有趣的功能,但有太多在这第一个测试一些其他的改进。

甲骨文虚拟机VirtualBox的4.0.0 Beta 1中也有各种错误,包括图形用户界面的调整,支持修复三维,二维视频多显示器布局加速支持,以及各种Linux和来宾增添修复。
