本机安装的是WIN 7 ，详细版本是：Windows 7 Ultimate, 32-bit 6.1.7601, Service Pack 1 。虚拟机版本:7.1.2 build-301548.在虚拟机上安装RED HAT ENTERPRISE LINUX 6 64版本时，报如下错误：

You have configured this virtual machine to use a 64-bit guest operating system. However, 64-bit operation is not possible. This host is VT-capable, but VT is disabled.

This is usually because VT has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting. Please:

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

(2) Power-cycle the host, if either of these BIOS/firmware 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/firmware to the latest version.

For more detailed information, see http://vmware.com/info?id=152.
Continue without 64-bit support?

然后不能启动，然后报如下错误：

This kernel requires an x86-64 CPU, but only detected an i686 CPU.Unable to boot - please use a kernel appropriate for your CPU.

只需在BIOS下开启虚拟化技术，即设置virtualization technology选项即可。（Intel系列的CPU芯片需要支持EM64T和VT，并且需要BIOS支持才行。）进入BIOS后，选择Security选项，然后选择

Virtualization选项，进去后把Inter(R) Virtualization Technology选项设置为Enable后，退出重启电脑，即可顺利安装RED HAT ENTERPRISE LINUX 6 64位操作系统
