ubuntu 會用 `/etc/machine-id` 來作為 DHCP identifier 去要 IP address 而 cloud image 裡面這個值是固定的 所以 clone 之後會拿到重覆的 IP 把 `/etc/machine-id` 清空即可 Solution: ``` virt-customize -a <img> --run-command "echo -n > /etc/machine-id" ``` Reference: https://knowledge.broadcom.com/external/article/316620/cloned-vm-acquires-the-same-dhcp-ip-addr.html
