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
In my environment, the problem occurred when I tried to start 20
instances in the same time with the following command.
nova boot --image IMAGE --num-instances 20 test
Some of the instances couldn't get dhcp IP address.
I found the following warning message in /var/log/quantum/server.log.
