Hi, I am trying to programmatically rebuild a nova instance that has a persistent volume for its root device. I am specifically trying to rebuild an instance that has multiple network interfaces and a floating ip. I have observed that the order in which the network interface are attached matters, floating ip attach to eth0 based. How do I figure out which of the interfaces currently attached is associated with eth0? -------------- next part -------------- An HTML attachment was scrubbed...
