There are a handful of steps to clean up the vm.cfg from the clone, which has details about the VM. If you don't change the MAC address (for instance), when you bring up the clone it will pull the NIC from the live system (one of those wonderful Oracle VM features). I am just trying to take a repetitive process and clean it up without direct human intervention. That will prevent human error (in case we miss something) and make it easier. I have all steps done except this one. If there is just one nic it works fine too, but when testing it out I happened to clone a system with 2 nics and I discovered the issue. I have some systems with 3 nics. I think I will have to script it as Kai said.
I know that messing with NIC MAC addresses can get you in trouble, but right now we are just doing the same thing manually. The clones don't usually last that long, and when done they are usually purged. I don't believe any of our current VMs have AA in the fourth octet (and if they did I could change it to something else), and then the last 2 octets are randomized.... chances of hitting an existing MAC are about nil. -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
