Virtual machine centos7 ens33 can surf the Internet, but it will not be able to access the Internet if changed to eth0

service network restart restart also failed.

I did it here https://blog.csdn.net/qq_3718.
https://www.cnblogs.com/gerry.

feels like the steps are all the same

it is said on the Internet that the hardware ID has changed, but I can"t find out what hardware ID should be changed

[root@localhost etc]-sharp dmesg | grep-I eth [1.347719] e1000
0000sharp dmesg 02grep 01.0 eth0: (PCI:66MHz:32-bit) 00:0c:29:67:ff:e3 [1.347738]
e100000001402sharp dmesg 01.0 eth0: Intel (R) PRO/1000 Network Connection

attach dmesg command, there is no so-called rename record

[3.057410] e1000 000000 blockquote 01.0 ens33: renamed from eth0

ifconfig shows ens33
