在CentOS 6 使用VMWare 啟動64Bit 的OS 出現VT 問題的解決辦法

我分別在兩台CentOS 6 (64Bit) 伺服器裡的VMWare 設定了一個新的Virtual Machine (CentOS 64 Bit), 而這個Virtual Machine 的VMDK 檔是從別架電腦拷貝過來的.  因此當我想要啟動時, 出現了以下的問題:

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

以及

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?

解決辦法:

1. 進入BIOS
2. 如果是Intel Processor, 尋找 "Virtualization Technology" (以DELL 伺服器為例, 是在CPU Information 這個選項裡) , 然後選擇 Enable
3. 如果是AMD, 尋找 "AMD V"  , 然後選擇 Enable
4. 儲存了之後重新啟動伺服器就可以了
5. 進入OS 之後打開VMWare, 再啟動一次Virtual Machine, 這次應該順利啟動了.
