解决centOS 7安装后无法上网+虚拟机不能安装问题
时间:2016-07-24 14:02 来源:linux.it.net.cn 作者:IT
已将该虚拟机配置为使用 64 位客户机操作系统。但是，无法执行 64 位操作。
此主机支持 Intel VT-x，但 Intel VT-x 处于禁用状态。
如果已在 BIOS/固件设置中禁用 Intel VT-x，或主机自更改此设置后从未重新启动，则 Intel VT-x 可能被禁用。
(1) 确认 BIOS/固件设置中启用了 Intel VT-x 并禁用了“可信执行”。
(2) 如果这两项 BIOS/固件设置有一项已更改，请重新启动主机。
(3) 如果您在安装 VMware Workstation 之后从未重新启动主机，请重新启动。
(4) 将主机的 BIOS/固件更新至最新版本。
有关更多详细信息，请参见 http://vmware.com/info?id=152.
解决方案：
进入系统的bios，进入到高级，将虚拟功能【Intel VT-x】打开。
问题2：连不上网
