本機安裝的是WIN 7 ，詳細版本是：Windows 7 Ultimate, 32-bit 6.1.7601, Service Pack 1 。虛擬機版本:7.1.2 build-301548.在虛擬機上安裝RED HAT ENTERPRISE LINUX 6 64版本時，報如下錯誤：
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.

Continue without 64-bit support?
然后不能啟動，然后報如下錯誤：
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下開啟虛擬化技術，即設置virtualization technology選項即可。（Intel系列的CPU芯片需要支持EM64T和VT，並且需要BIOS支持才行。）進入BIOS后，選擇Security選項，然后選擇Virtualization選項，進去后把Inter(R) Virtualization Technology選項設置為Enable后，退出重啟電腦，即可順利安裝RED HAT ENTERPRISE LINUX 6 64位操作系統.
記住：有些主板BIOS設置里面可能沒有Virtualization選項，必須先去配置里面選擇Virtualization，然后選擇View(可見)，然后去Security里面Enable即可。
