Floating IP taking 2 minutes to be assigned to a VM

Asked by Dimitri Souza


In a Flat DHCP network configuration, using ESSEX configured to auto-assign floating IP addresses to the instances, OpenStack is taking up to 3 minutes after the VM instance becomes active to show up the floating IP assigned to the instance (via "nova list").

I noticed that the Floating IP is already allocated to a specific instance (via "nova-manage floating list" I can see the ID of my instance in the allocated floating IP), but it takes up to 3 minutes to this floating IP to appear via "nova list".

Is there any nova configuration that I could set to eliminate this 3 minutes gap between the instance becoming active and the floating IP being available via 'nova list'?
