Thanks again vish<br><br>Do we have any roadmap to include a functinality for using ISC-dhcp and bind dns as default in openstack. As with the release of Bind 10 a lot of functionality would be getting change from how bind9 worked. Now ISC-dhcp would be saving lease files in database and lot more.<br>
Even moinmoin project running to provide DNSaas in openstack that supports bind 9 at present would there be any future change in nova dhcp and dns architecture to the currently it has. <br><br><div class="gmail_quote">On Wed, Feb 20, 2013 at 1:30 AM, Vishvananda Ishaya <span dir="ltr"><<a href="mailto:vishvananda@gmail.com" target="_blank">vishvananda@gmail.com</a>></span> wrote:<br>

<div style="word-wrap:break-word">You cannot have an external dhcp server with openstack. Openstack needs a way to know the ip address assigned to a vm to do its listing properly. If you don't care about the api returning valid ips there is a possibility of using FlatNetworking (not FlatDHCP) to make nova stick the network into a bridge and not do any dhcp at all. You could then have an external server serving up dhcp ips. I suspect you will probably have to disable security groups completely using NoopFirewallDriver driver to get this to work.<div>
