Stein: Error while executing command: HttpException: 503, Unable to create the network. No tenant network is available for allocation. [closed]
Im installing OpenStack Stein in RHEL7, i have followed the official installation guide. I have installed networking service option 2. When i try to run the command:
openstack network create selfservice
I got following error:
Error while executing command: HttpException: 503, Unable to create the network. No tenant network is available for allocation.
i have also followed the answer given in the link
https://ask.openstack.org/en/question/85338/neutron-net-create-unable-to-create-the-network-no-tenant-network-is-available-for-allocation/
The configuration of /etc/neutron/plugins/ml2/ml2_conf.ini file is
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
[ml2_type_flat]
flat_networks = provider
[ml2_type_vxlan]
vni_ranges = 1:1000
[securitygroup]
enable_ipset = true
The openstack network agent list is working fine.
[root@controller openstackusr]# openstack network agent list

1 set debug=true in /etc/neutron/neutron.conf
2 restart all neutron services
3 jjournalctl -f > debug.log
4 penstack network create selfservice
5 stop journalctl -f
6 ocate the problem in debug.log
or just check neutron server log.
Looking at the code, it would seem you make a mistake when creating the external network. Can you share how you did it?
Also the message and its context in the neutron server log.
Thanks Bernd , i had missed to create provider external network.
