Hi all,
As per the subject, It seems I can't create a tenant network in case the
provider network has been configured as flat.
That's the way the system looks now:
[wrsroot at controller-0 ~(keystone_admin)]$ system host-if-list controller-0

If I try to create a tenant network now, I get:
[wrsroot at controller-0 ~(keystone_admin)]$ openstack network create new_nw
Error while executing command: Unable to create the network. No tenant
network is available for allocation. (HTTP 503) (Request-ID:
req-14d0ad64-cdc4-47f4-9b43-4299a3aec8d5)
In case of a "vlan" provider network I have no limitation.
Any suggestion ?
Many thanks
