...adding a few thoughts around this proposal. There are times when we need to preserve the IP/MAC address(s) for VM migration for things such as: 1. Licensing tied to the IP/MAC address 2. Complex configurations such as HA clustering 3. Anytime network preservation is needed to run post configuration playbooks in some migration solutions 4. Using in OS agents to manipulate networking may not be feasible for all With the patch Richard is proposing it addresses the above items. My suggestion is if MAC/IP preservation isn't desired then don't use the --mac address option. If the --mac address option is used maybe flag it with --preserve if persistence is desired/needed. This should tackle both perspectives on if/should/could/need/don't. :) -- Brett Thurber - RHCA, RHCVA Engineering Manager and Sr. Principal Software Engineer, Solutions Engineering Products & Technologies Group, Red Hat Mobile: +1 (512) 547-9282
