All looks ok on the provider side, the ovn db is populated properly. The OVN docs: http://openvswitch.org/support/dist-docs/ovn-nb.5.txt it seems that this option is not mandatory (the mandatory one's being listed a paragraph higher). I'm inquiring with the OVN team if this is indeed so, and if so, why dhcp fails to work. According to findings by the OVS team, the problem is resolved in OVS 2.8 Until we move over to 2.8 the default gateway will still be mandatory. Currently we can not move to 2.8 until BZ 1503820 is fixed. The OVS patch that changes this (if you are interested): https://github.com/openvswitch/ovs/commit/b89d25e5694bc9bb0a1fbb2a025d18a2a231c633 Note that the docs on the ovs site already state that the default gateway is optional, as these are the docs of the master branch, and are already updated. verified on: ovirt-engine: 4.2.5.2-0.1.el7ev ovn: ovirt-provider-ovn-1.2.13-1.el7ev.noarch ovs: openvswitch-2.9.0-55.el7fdp.x86_64 |
