This is because the directly copied virtual machine also copies its mac address, and thus cannot be used in the new virtual machine. Solution: 1. delete/etc/udev/rules. d/70-persistent-net.rules 2. restart the virtual machine. the file is automatically generated in linux, and then you can access the Internet by configuring the network.
