<div>If you are using neutron with overlapping IPs, you will run into problems where tenants can modify another tenants address (overlapping IPs).

<div>Right now designate is promoting to OS
core (in icehouse). <br>
But last time I run it (~month ago), it was bit messy. Hope they
clean it up prior icehouse release.<br>

Neutron DNS name does not match VM hostname</font><font size="3">
</font><font face="sans-serif" size="3"><br>
On our Havana openstack running on redhat we're seeing a
situation where
VM hostname doesn't match the DNS name. <br>
The default hostname which is given by dns is "host-ip-address"
and not the real hostname of the VM. <br>
<br>
Is there any fix that can resolve this problem ? <br>
<br>
Thank you. <br>
