VirtualBox 3.2.6 Final

秋子淡无痕

VirtualBox最早是德国一家软件公司InnoTek所开发的虚拟系统软件,后来被Sun收购,改名为Sun VirtualBox,在Sun被Oracle收购后现改名为Oracle VirtualBox.因为他是开源的,不同于VM,而且功能强大,可以在 Linux/Mac 和 Windows 主机中运行, 并 支持在其中安装 Windows (NT 4.0、2000、XP、Server 2003、Vista)、DOS/Windows 3.x、Linux (2.4 和 2.6)、OpenBSD 等系列的客户操作系统.假如你曾经有用过虚拟机软件的经历的话，相信使用 VirtualBox 不在话下。即便你是一个新手，也没有关系。VirtualBox 提供了详细的文档，可以助你在短期内入门。

    * VMM: allow 64-bit SMP guests on 32-bit hosts (VT-x and AMD-V only; does not apply to Mac OS X, which already supports it)
    * VMM: fixed Guru mediation if guests with more than 2GB are booted with VT-x/AMD-V disabled (bug #5740)
    * VMM: fixed TR limit trashing (VT-x and 64-bit host only; bug #7052)
    * Page Fusion: several bug fixes for SMP guests (including bug #6964)

    * LsiLogic: fixed hang with older Linux guests
    * BusLogic: fixed hang during I/O
    * SATA: set initial number of ports to 1 as some guests can't handle 30 ports (e.g. CentOS 4 and FreeBSD; bug #6984)

    * E1000: disconnect cable was not properly handled if the NIC was not yet initialized by the guest
    * OVF: export performance optimization
