Ok, thanks. Where is the DHCP agent running? You need to make sure that the agent is connected to the DVS that you are using in Nova. In addition to this you need to make sure that it can use MAC’s that are allocated by OpenStack.

Wherever it's running will need to have OVS installed and be registered into NSX as a "hypervisor" so that the DHCP agent can be plumbed into the overlay networks. One common arrangement is to build a Neutron "network node" that is running the DHCP agent and metadata agent, and register that into NSX.

At this time, I don't believe it's OVS 2.5.0 (as noted in your command-line installation of OVS). how to I ensure the supported version is installed. is there a support matrix? if so could you please share it? -- Scott -- Regards, Vaidyanath +91-9483465528<tel:%2B91-9483465528>(M) -- Regards, Vaidyanath +91-9483465528(M)
