乱七八糟的吧？！在解释这一点时，我会尽量不误导您……我正在尝试模拟几天后必须配置的环境。所有操作系统都是 64 位的。我的开发机器上有 Windows 7，在 VirtualBox 上运行无头 Ubuntu 服务器 12.04（操作系统应该安装在即将到来的服务器上）。在 Ubuntu 上，我正在尝试将“Windows 7”安装为虚拟机，直到它功能齐全并开始在其上安装其他应用程序。
图像（托管在无头 Ubuntu 服务器上的 Windows 7）启动并显示 windows 正在“加载文件”，而不是启动安装过程，它显示消息：Attempting to load a 64 bit application however this cpu is not compatible with 64-bit mode.
以下是 Windows 7 虚拟机信息：

那么我在这里缺少什么？可能是不可能在虚拟机（无头 Ubuntu 服务器）上进行硬件虚拟化吗？
