Open Stack

Unfortunately, I create two subnets like this :

neutron subnet-create 9bca94f8-3986-4900-a64e-e7f0cfc4c934 10.10.10.0/24
--service-types list=true network:router_gateway --enable_dhcp=False
neutron subnet-create 9bca94f8-3986-4900-a64e-e7f0cfc4c934 20.20.20.0/24
--service-types list=true network:floatingip --enable_dhcp=False

As shows above, one for router's gateway and the other is for floatingip.

But exception occurs again in neutron server, like this:

" IpAddressGenerationFailureNoMatchingSubnet: No valid service subnet for
the given device owner. "

Details info at [1].


Could you give some advice?


Thanks
