i am trying to complete an openstack installation
openstack version: 3.8.1, OCATA
i have done everything as should and now since i have complete the openstack installation i am trying to create a new instance but i cannot.
i want to create a new instance but in order to do that i have to create a network first and a subnet.
when i try to create a network and subnet from horizon i get an error: Error: Failed to create network "network1": Unable to create the network. No tenant network is available for allocation. Neutron server returns request_ids: ['req-d66b6ec9-fb16-4477-9ca8-f4a287a3a344']
after that i exectuted the following through cli:
openstack subnet create --network provider --allocation-pool start=[login to view URL],end=[login to view URL] --dns-nameserver 220.127.116.11 --gateway [login to view URL] --subnet-range [login to view URL] provider
openstack network create --share --external --provider-physical-network provider --provider-network-type flat provider
and a subnet and nwetwork were create succesfully
(through dashboard i still get the same error, but since i did that through cli i tried to proceed with instance creation)
then i went to create a new instance via horizon but i get an error at the end of the procecss and the new instance is not created:
Error: Failed to perform requested operation on instance "inst1", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].

so i am at this poinr right now, i just need your help to fine tune it, so i can create instances and check if ips are assign correctly
i need an expert in openstack ocata who will be connected in my pc with teamviewer and fix the problem
i use ubuntu 16.04 on my server
thank you in advance
