VM不能安装64位操作系统

其实下文讲了这么多,主要就是进入BIOS中将电脑的虚拟化(VT/Virtualization)打开,它在Advanced BIOS Features选项下

  VM有这么一个提示:

This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.

This host is VT-capable, but VT is disabled.

VT might be disabled if it has been disabled in the BIOS settings or the host has not been power-cycled since changing this setting.

(1) Verify that the BIOS settings enable VT and disable 'trusted execution.'

(2) Power-cycle the host if either of these BIOS settings have been changed.

(3) Power-cycle the host if you have not done so since installing VMware Workstation.

(4) Update the host's BIOS to the latest version.

For more detailed information, see http://vmware.com/info?id=152.

Continue without 64-bit support?

  这段提示的关键就是“VT”, VT就是“Virtualization Technology(虚拟化)。

  第一,CPU要为64位。

  第二,CPU要支持VT技术。

  第三,主板Bios设置要打开VT。

  前两项可以用securable来检测。

  “hardware D.E.P”,此项与VM安装64位操作系统无关。简而言之,DEP(数据执行保护),是windows针对溢出的一种保护措施。

  “64 Maximum bit length”,是指该CPU为64位的CPU;有的CPU虽是32位的,但用“securable”检测出来也是64,这说明该CPU也支持64位系统,可以安装64位系统。

  “YES Hardware virtualization”,是指该CPU支持硬件虚拟化,如果此项显示为“YES”的话,说明你的CPU支持VT技术,如果还不能在VM中安装64位系统的话,就说明BIOS中此CPU VT功能没有开启。(有的securable版本会显示“Locked ON、Locked Off”,意思类似。)

  这时就需要在“主板Bios当中要打开VT”功能。
