Public bug reported:
When a network contains several subnets (especially ipv4 + ipv6) DHCP
agent may spawn dnsmasq incorrectly, so tag in the command line (--dhcp-
range) will not match the tag in opts file.
This leads to a state when dnsmasq sends it's IP address as a default
gateway.
As a side effect, VM's floating ip snat traffic begin to flow through
dhcp namespace of the server that has given an ip address to that VM.
