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
