As I understand from the video you posted at the thread beginning, produced QEMU virtual machine doesn't have a network connection. How did you come to this? "ping" will not work for QEMU machines by default, but the network should work. You could try to open a web-page with a browser or do anything except programs like "ping" which uses (ICMP protocol).
