--Sig_/VGMKTYdpfCl66PXM9RKH.s2 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hello, I have an oVirt 3.5.x install on CentOS 7.1, and I'm trying to wrap my head around how to use the Neutron appliance. In the video demo, two hosts attach the neutron network to their eth1 interfaces, and their VMs can communicate with each other. But the demo doesn't go on to show how to connect those VMs to the internet with floating IPs. In the OpenStack Neutron videos I've watched on youtube, the common basic configuration seems to be a single 'network node' that connects to the public and private networks and routes to the 'compute nodes', which aren't connected to the public network. With the oVirt/Neutron integration, it seems like all hosts are both 'network' and 'compute' nodes, meaning that they need to be connected to the public network. Is that right, or am I missing some fundamental concept? Is it possible to designate 1 or 2 hosts of a cluster (with public network access) for the neutron appliance, while the remaining hosts only have private network access + floating IPs for VMs?

Depends on your setup... Are you using gre/vxlan with ovs on the hosts, or are you using the Linux bridge? On Jul 29, 2015 12:34 AM, "Robert Story" <rstory@tislabs.com> wrote:

Are you using gre/vxlan with ovs on the hosts, DD> or are you using the Linux bridge? Right now I'm still in the planning stages. I've got the hosted engine up on one host, but haven't gotten gotten the neutron appliance up yet because I wasn't expecting it to need its own nic/interface. Maybe some information about my setup will help.. I've got a lab and a server room, each with their own public ip space. The server room has internal and external production systems, and the lab has test some important-but-not-production systems. Right now all these systems are connected to both public and private networks through multiple interfaces or vlans. I'd like to use neutron to eliminate the direct connection to the public networks and use floating IPs instead. I'd also like to isolate the internal production from public facing production, and lab test systems from lab important systems. I should add that I'm not a sysadmin, but a developer who was nominated to administer group resources. So I'm learning as I go. I've been running oVirt 3.4 in the lab for a few months, and now am wanting to get oVirt 3.5 into the server room (and eventually to migrate the lab systems to a second 'data center' of the server room install). Any thoughts or suggestions welcomed, on or off list.
