我正在尝试启动一个 Windows Oracle 虚拟机，但是当 VM 启动时，我收到此错误：

VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
Result Code:
NS_ERROR_FAILURE (0X80004005)
Component:
ConsoleWrap
Interface:
IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

我试过了，但它没有改变任何东西：virtualbox NS_ERROR_FAILURE (0x80004005)没有找到任何东西，因此我完成了所有 3 个步骤。

我不确定如何进一步调试，感谢任何帮助。
