開源的虛擬機器軟體 VirtualBox v1.5.2

對於VMWare、Virtual PC這些虛擬機器軟體，可能大家都比較熟悉。VirtualBox是德國一家軟體公司InnoTek所開發的虛擬系統軟體，它不僅具有豐富的特色，而且效能也很優異。更是開源的，成為了一個發布在GPL許可之下的自由軟體。VirtualBox 可以在 Linux 和 Windows 主機中運行，並支援在其中安裝 Windows (NT 4.0、2000、XP、Server 2003、Vista)、DOS/Windows 3.x、Linux (2.4 和 2.6)、OpenBSD 等系列的客戶作業系統。假如你曾經有用過虛擬機器軟體的經曆的話，相信使用 VirtualBox 不在話下。即便你是一個新手，也沒有關係。VirtualBox 提供了詳細的文檔，可以助你在短期內入門。
在10月18日已更新到了 1.5.2 版。這隻是一個 bug 修訂版本，主要解決了在圖形化使用者介面、BIOS、VGA、VMM、網路、以及 VRDP 等方面的問題。此外，VirtualBox 1.5.2 也包括些許改進，如改進了在 Linux 主機上的鍵盤處理、NLS、與 Linux KVM 的相容性、MAC 位址處理，在 VM 關閉對話方塊中增加了 ACPI 關機選項，支援其他的 RDP 用戶端，Linux 附加程式支援 X.org Server 1.4 等等。
