解決centOS 7安裝後無法上網+虛擬機器不能安裝相關問題

已將該虛擬機器設定為使用 64 位元客戶機作業系統。但是，無法執行 64 位元操作。
此主機支援 Intel VT-x，但 Intel VT-x 處于禁用狀態。
如果已在 BIOS/韌體設定中禁用 Intel VT-x，或主機自更改此設定後從未重新啟動，則 Intel VT-x 可能被禁用。
(1) 確認 BIOS/韌體設定中啟用了 Intel VT-x 並禁用了“可信執行”。
(2) 如果這兩項 BIOS/韌體設定有一項已更改，請重新啟動主機。
(3) 如果您在安裝 VMware Workstation 之後從未重新啟動主機，請重新啟動。
(4) 將主機的 BIOS/韌體更新至最新版本。
有關更多詳細資料，請參見http://vmware.com/info?id=152.

解決方案：
進入系統的bios，進入到進階，將虛擬功能【Intel VT-x】開啟。

問題2：連不上網
