Description Perry Myers 2013-01-13 15:12:41 EST
Change Quantum DHCP agent to use RPC rather than notifications
Comment 1 Gary Kotton 2013-05-14 04:43:23 EDT
This is part of the Grizzly release.
Comment 4 Rami Vaknin 2013-05-23 15:58:50 EDT
Could you please specify what should be tested here? Does basic DHCP functionality imply that RPC works well?

I'll have to defer to the Quantum devs to answer that question.
Comment 6 Gary Kotton 2013-05-26 12:31:48 EDT
The basic functionality of the DHCP service needs to be verified.

In Folsom when a subnet was created a notification would be sent and any DHCP agent could pick up the notification.

In Grizzly the agents are registered with the plugin and the communication is done directly with the agent via the standard RPC channels.
Comment 7 Rami Vaknin 2013-05-28 05:32:46 EDT
Verified on Grizzly installed on RHEL6.4, openstack-quantum-2013.1.1-8.el6ost.

The dnsmasq process has started successfully (after removing libvirt's dnsmasq process) and an instance got his ip.
