In Essex, I've seen issues like this if your fixed_ips table in the nova database has multiple entries for the same address (even if some of those entries are marked delete=true, though this has been fixed in Folsom). If you feel confortable, take a look at the fixed_ips table to see if anything looks odd. The dnsmasq conf files are generated directly from this table.
