After centOS 7 is installed, the system cannot access the Internet + the VM cannot be installed.

After centOS 7 is installed, the system cannot access the Internet + the VM cannot be installed.

The virtual machine has been configured to use a 64-bit client operating system. However, you cannot perform the 64-bit operation.
This host supports Intel VT-x, but Intel VT-x is disabled.
If you have disabled Intel VT-x in BIOS/firmware settings, or the host has never restarted since the settings have been changed, Intel VT-x may be disabled.
(1) confirm that Intel VT-x is enabled in BIOS/firmware settings and "trusted execution" is disabled ".
(2) If either of the two BIOS/firmware settings has been changed, restart the host.
(3) If you have never restarted the host after installing VMware Workstation, restart the host.
(4) Update the BIOS/firmware of the host to the latest version.
For more details, see http://vmware.com/info? The id = 152.

Solution:
Enter the system bios, enter advanced, and enable the virtual function [Intel VT-x.
