from backend, it would remain same for virtual network. For macvtap,
validation of interface would be okay since interfaces listing is
moved to gingerbase and kimchi is using it for networks hence same
code can be utilized. For openvswitch, ginger code will have to be
moved to gingerbase to enable kimchi to list host ovs interfaces.
On high level I
guess below needs to be done, and both point below are
independent of each-other.
1) Listing of networks based on selected type. (This will mostly use to
show list in UI, based on type).
2) Once network is selected/provided, an REST API call which will land
to control and model. From control point of view it will be addition of
parameters. And from model point of view, we need to add if and else to
check type.
And for virtual type, existing code implementation should work. And for
other two type, we need add code for addition of these options in
template params. And also code to generate corresponding xml based on type.
It will be mostly on template/guest edit/create code and network
add/remove from guest/template.
May be validation of network(s) to check if network(s) exist( for type
macvtap and ovs) or not can be done as improvement to feature.
