you always get a fixed ip

do you have a machine with the hostname sonoma? Perhaps you did at one point and the hostname has changed?

I suspect either:

a) you have a network or fixed ip with an old hostname assigned:
mysql nova -e 'select * from fixed_ips where host="sonoma"'
mysql nova -e 'select * from networks where host="sonoma"'

or (more likely)
b) you are running multi_host mode and you have nova-compute running on the host 'sonoma' and you don't have nova-network running on the host like you should.
