##### SUMMARY
<!-- Explain the problem/feature briefly -->
If physical KVM host IP address changes with DHCP, the agent is unable to reconnect to CloudStack management server.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
Change the IP address of the KVM node the agent is running on and reboot the host.
The agent will not be able to connect back to the management server and throw errors.
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
The agent should connect back to management server, and the host physical IP address should be updated.

@damonb123 by design, DHCP enabled KVM hosts aren't support with the CA framework security enabled. You can disable the auth strictness on such hosts to make them work. Though it's not a good idea to have hosts whose rfc1918 IPs can change.

Could you try having static DHCP assignments by your router?

@damonb123 Static assignment should always be preferred for your hypervisors for various reasons. Try setting static DHCP assignment on your DHCP server of the host's management MAC address to always lease a static IP.

@damonb123 It sounds to me your scenario would have to be;
- remove the host from cloudstack
- change the ip
- reboot
- re-add
I don´t think we support this out-of-bounds changing of the IP of an host.
