According to message "duplicate dhcp-host IP address 10.5.0.2", there should be multiple entries of the same IP 10.5.0.2 in file /var/lib/quantum/dhcp/864facd7-0179-40fe-8928-48c3993b8c00/host, while MAC addresses of the entries may be different.
It seems that in the case dnsmasq server will report error and doesn't allocate IP address for the DHCP request. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189909 Title: dhcp-agent does always provide IP address for instances with re-cycled IP addresses.
