> Hi;
> Today we noticed that one of our new provisioned instance did not get IP
> from VR. When we dig into the issue we find that one different mac is
> written in dnsmasq.leases file holds new instances IP address.
> We checked this mac address from db and we noticed that this mac is used
> for old expunged instance.
> So from this point we realised that when we destroy an instance its mac did
> not removed from dnsmasq.leases file so if we use this ip for a new
> instance then we have a problem, our instance could not get IP from VR.
> We have one host on our lab environment and its Ubuntu 16.04.3 KVM. Today
> we made a HA test and we crashed the host so VR and SystemVM's are rebooted
> after we boot host back. I do not think this issue is related to VR reboot
> but i like to give information about our environment.
> We need to manage dnsmasq.leases file when we expunge an instance.
> Thanks
> Özhan
