Bug Description
When dnsmasq is restarted, it forgets about all leases (since it runs with leasefile-ro option). When client tries to renew its lease, dnsmasq sends DHCPNAK reply with message "lease not found". Then client shuts down the network and re-request lease from DHCP server (and gets exactly same IP address). There's a small network downtime which affects services, like zookeeper, running in VMs.
dnsmasq have special option, --dhcp-
TL;DR - option "--dhcp-
