+++ This bug was initially created as a clone of Bug #1254213 +++
Description of problem:
It would be very useful to be able to define virtual networks encapsulated a-la OSP, where not mapped networks to existing physical nics on hosts, could allows vm's to communicate between each other while isolating traffic.
This could allow to define set of vm's with backend/frontend networks with Vm's on different hosts .
As per our last OVN session:
In oVirt engine, when we try to create OVN network subnet, without specifying IP gateway, the engine throws unfriendly (generic) error. In the background, OVN provider throws exception for missing IP gateway. In Neutron, the behaviour is different. We don't need to specify a gateway and it is calculated from the given CIDR. If we don't want to handle this scenario, we should at least document that the provider requires IP gateway address.
Verified on version:
I've added doc text appropriate for a release note based on the text in the feature page. Marcin, can you please check that it is correct?
I'll create a docs bug with the links from the original doc text shortly.
" and import networks from it to Red Hat Virtualization"
We can both import networks, or create new ones from RHV.
Maybe something like: ", import network into RHV, or create new external OVN networks from RHV"
"You can then define logical overlays"
I would say a network represents a logical overlay.
Maybe: "You can then use these logical overlays (OVN networks) to provision ..."
Thanks Marcin. Text updated.
