Hi, The documentation http://docs.openstack.org/diablo/openstack-compute/admin/content/configuring-flat-dhcp-networking.html has the passage: "The nova-network service will track leases and releases in the database so it knows if a VM instance has stopped properly configuring via DHCP" Can someone briefly explain me what this means, if possible with rough pointers to code? I don't recall nova noticing when my VM actually stopped properly configuring via DHCP. -- Eugene Kirpichov http://www.linkedin.com/in/eugenekirpichov
