Devin,
I presume the OVN Controller should just be some VM that is on the ovirtmgmt network, or is there a preferred place to install the OVN controller software?
Please note the difference between OVN-Central and OVN-Controller: OVN-Central is the central part of OVN, storing the logical configuration and controlling the many OVN-Controllers OVN-Controller is the piece of software which resides on the ovirt-hosts, and manages the local OVS setup on the host. OVN-Central / | \ / | \ / | \ / | \ OVN-Controller OVN-Controller OVN-Controller OVN-central can be installed anywhere , as long as it can communicate with the engine and all the hosts. During development we install it along the ovirt engine for convinience. OVN-Controller must be installed on every ovirt host.
I then also assume I install the OVN agents onto all the oVirt Nodes.
Short answer: Yes Longe answer: If you plan not to use external networks on some clusters, you can skip its hosts. You can choose the clusters which support the external network by assigning the network to clusters.
I see that when you go to add the External Provider, does OVN Controller use authentication, is there any information I would need to have besides knowing which node it's on in order to add it to external provider?
For now it is only the url of the provider. The provider is still under development, authentication is still just an empty mock.
Would I need to have any bridges or OVS configured on the nodes for this to work or just install the services and get them configured and it just works?
We are using the default 'br-int' bridge which OVN is using. All should be configured when OVS/OVN is installed. Let me know if I can help with anything else. Marcin ----- Original Message -----

I have manually created the RPM's successfully, I just want to clarify a few items so I make sure I'm deploying this according to best practice.
I presume the OVN Controller should just be some VM that is on the ovirtmgmt network, or is there a preferred place to install the OVN controller software? I then also assume I install the OVN agents onto all the oVirt Nodes. My take on this is that this OVN replaces the more complex Neutron/OVS installation, and makes for a more simple deployment.

Your assistance is appreciated.

Devin,
The openvswitch OVN packages must be build manually at the moment. It is still not available either in the repos, nor as a download. For now please use the procedure attached below to build the OVN rpm's.
I am not sure where 'firewalld-system' comes from. Is it not 'firewalld-filesystem'? This should be available from the standard repo.
The ovirt-provider-ovn is being developed quite actively, and the blogpost is already somewhat outdated (even though it's not even a month old). I will try to update it asap.
Thanks, Marcin
BUILDING PROVIDER RPMS: ---------------------- git clone https://gerrit.ovirt.org/ovirt-provider-ovn make rpm
BUILDING OVN RPMS: ------------------
Clone the repository:
git clone https://github.com/openvswitch/ovs
Install the following packages, as they are need to build ovn:
yum -y install gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake rpm-build redhat-rpm-config rpm-build rpmdevtools bash-completion autoconf automake libtool PyQt4 groff libcap-ng-devel python-twisted-core python-zope-interface graphviz openssl-devel selinux-policy-devel
Build the ovn rpms:
cd ovs ./boot.sh ./configure make dist cp openvswitch-<version>.tar.gz $HOME/rpmbuild/SOURCES cd $HOME/rpmbuild/SOURCES tar xzf openvswitch-<version>.tar.gz cd openvswitch-<version> rpmbuild -bb rhel/openvswitch-fedora.spec
The built rpms will reside here: ~/rpmbuild/RPMS/x86_64/

Yaniv,
I am looking at the page that talks about ovirt-provider-ovn, and it sounds like something I want to try. However the document seems to be
not
complete, and I'm not sure i fully understand how it should be deployed. When I downloaded the "ovirt-provider-ovn-driver-0-1.noarch.rpm" and
to install on the oVIRT nodes it complains about needing other packages such as:
- openvswitch-ovn-central - python-openvswitch - firewalld-system - openvswitch-ovn-host
I don't see anywhere where it talks about getting access to the RPMS for openvswitch-ovn-central. Also I presume like Neutron I would install OVN on a Master node and then install some clients on the nodes? Can you
me additional information on this?

We are working on a native path to SDN via OVN (experimental at this point): https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/
Using Neutron is an option, but at some point the native option might be easier to use (we want to add a UI for it and tighter integration).

oVirt Users:
My work is currently deploying oVirt 4.0.5 into our Development environment. I see there use to be a maintained Openstack Neutron image that could be used with oVirt to provide SDN functionality. I'm suspecting that the reason for the image no longer being maintained is because it became a hassle to keep updated and patched. From what I understand
current idea is to just point your oVirt installation to an already installed Openstack setup. I can easily install an image and install
----- Original Message ----- try provide the the
latest Openstack (Keystone/Neutron) and then point oVirt to it, but I want to understand if that is the proper way to move forward. Is there a general consensus with the way oVirt is moving in regards to Software Defined Networking and Neutron in general? Just want to ensure I understand it clearly before just installing my own Neutron if there is going to be another method.
Any feedback is appreciated.
