Re: [ovirt-users] oVirt 3.5 & Neutron (Will this work?)

Hi Phil, See answers/questions inline. ----- Original Message ----- A new host is not mandatory. You need to move an existing host to maintenance and reinstall it. On the "Re-install" dialog select the details of the network provider. Do you intend to use a single neutron appliance for each host or to use a single neutron appliance to manage connectivity on the two hosts ? Is there L2 connectivity between the hosts ? Or by "not connected to anything" you actually mean there is no wiring between the hosts ? If this is the first case, you should be able to define for each subnet a gateway via the 'Add subnet' dialog on the engine. That gateway should be used for obtaining connectivity for the vms to the public/external network. You'll have to configure it manually though (doesn't covered as part of the ovirt-neutron integration). If there is really no connectivity between the hosts and the only outgoing traffic from each host is via the ovirtmgmt network - it is problematic. According to [1], you'll have to specify as bridge mappings on the network provider agent details: br-neutron:ovirtmgmt, where ovirtmgmt will replace the neutron. But that also implies that you'll share any traffic going through the integration bridge of neutron and the hosts with the management network and respectively with the public network, hence the dhcp agents connected to br-int (which is connected to br-neutron and to ovirtmgmt) will receive request from the 'ovirtmgmt' network as well. Haven't tried it myself, and can't expect the results. [1] http://www.ovirt.org/images/2/2a/Neutron-appliance-topology.png
