我在笔记本电脑中使用 kubuntu，我已经在 kubuntu 14.04 lts 中安装了虚拟机，但是当我启动虚拟机时出现错误：
无法为虚拟机 ub 打开会话。
VT-x 在 BIOS 中被禁用。（VERR_VMX_MSR_VMXON_DISABLED）。
结果代码：NS_ERROR_FAILURE（0x80004005）组件：控制台接口：IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6
我的 kubuntu 的详细信息是
Linux Tank-PC 3.13.0-27-通用 #50-Ubuntu SMP 2014 年 5 月 15 日星期四 18:06:16 UTC x86_64 x86_64 x86_64 GNU/Linux

帮助我，大家...每一个答案都会很感激，谢谢
答案1
您只需重新启动计算机，进入 BIOS 设置并启用 VT-x。完成后，再次启动 Ubuntu，VirtualBox 就不会出现该错误。
答案2
您需要在 BIOS 中进行这些更改。此外，在按上述方法启用后，您可以从“/proc/cpuinfo”确认支持的指令集/标志。查找 vtx 或 vmx 标志是否在 CPU 上有 virt-support。或者尝试“lscpu”命令并查找“Virtualization: VT-x”
