Error: Error fetching floating ips

It seems like nova-network not response to your request.
Can you put the output of below command, maybe some nova service is not
running:
nova-manage service list

Yes, of course:

This is my /etc/network/interfaces settings:
http://pastebin.com/y617ZPmE

Note that my private network NIC is wlan card.

I'm starting to think that it's because NIC settings, since when I change:
# Private
auto wlan0
iface wlan0 inet dhcp

To:
# Private
auto wlan0

I no longer receive the error, but when I launch a new instance, it gets Network error while it's building.

Sorry!

This is before removal of "iface wlan0 inet dhcp":

There is some SQL connection error?
