我有一台 Dell Precision 笔记本电脑，型号为 M4400，配备 Intel Core 2 Duo P8600 处理器。在 BIOS 中，有多个选项可用于启用虚拟化技术 (VT-x)。我已将所有这些选项都设置为 ON。我的问题是，Virtual PC 2007 和 Sun 的 VirtualBox 都不允许我在该系统上使用 VT-x。
主机操作系统：Windows Vista Enterprise SP1（64 位）
感谢您提供的任何信息或见解。对于技术含量更高的人，这是我启动 Ubuntu 客户机时生成的 VirtualBox 日志文件：

答案1
我揭开了谜底。在 M4400 的 BIOS 中，有 3 个虚拟化选项。其中一个选项称为“受信任执行”，我已将其打开。尽管我的 TPM 已启用，但由于某种原因，此设置导致系统无法识别 VT-x。一旦我在 BIOS 中的“虚拟化”部分下禁用“受信任执行”，我就能够在 Virtual PC 和 Sun xVM VirtualBox 中使用 VT-x
答案2
安全应该告诉您硬件虚拟化是否已正确启用。
另外，您运行的是最新的 BIOS 吗？有些戴尔机型有 VT-X 处理器，但直到应用了最新的 BIOS 软件后才起作用。
答案3
我会打电话给戴尔。这不是你想要的答案，但如果你的硬件有问题，他们会帮你找到原因。这台笔记本电脑上的所有部件都应该能让你毫无问题地使用 VT-x。
答案4
我遇到了这个问题，发现 SpaceManSpiff 的关机解决方案完全解决了这个问题。我有一台配备 Intel Core Duo P9500 的 Dell E6400。
我遵循的步骤：
- 安装了 Virtualbox 3.1.0 主机 Windows Vista，客户机 Ubuntu
- 虚拟盒进入设置|系统|处理器；将其设置为 2 个处理器
- 启动机器
- 收到“VT-x 不可用”
- 重新启动并按 F2 进入 BIOS，启用
- 收到“VT-x 不可用”
- 使用“securable.exe”http://www.grc.com/SecurityNow.htm发现 VT-x 仍然处于禁用状态
- 拿出来，搜索了很多，找到了 SpaceManSpiff 的帖子
- 关闭电源并拔出电池（不确定电池是否有任何区别）
- 通电后即可工作！
我很高兴我的虚拟机终于有了两个处理器！
