> Key: CLOUDSTACK-2299
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2299
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Components: Network Controller, Network Devices
> Affects Versions: pre-4.0.0, 4.0.0, 4.0.1
> Environment: Virtual Router used for DHCP, DNS services
> Reporter: Dennis Lawler
>
> Commit c9c68e1 fixed a 2 second DNS outage triggered with new VM instantiations, but introduced a different problem: old DHCP leases are maintained in memory by dnsmasq.
> This causes IP re-allocations to fail as such:
> dnsmasq-dhcp[pid]: not using configured address 192.168.1.100 because it is leased to aa:bb:cc:11:22:33
> dnsmasq-dhcp[pid]: DHCPDISCOVER(eth0) aa:bb:cc:22:33:44 no address available
