This issue was discussed in [1], and is fixed as part of the bug
CLOUDSTACK-5967. So 'Ovs' is added as provider of 'Connectivity' service
as part of the fix. You need to create a network offering with 'Ovs'
selected as 'Connectivity' service provider. When you create network with
such network offering you should see tunnels established as well. There no
ui support unfortunaley , so you need to use api. Please see [2] for
sample api call to create network offering with 'Ovs' as 'Connectivity'
service provider
