Then I create a network, "openstack network create --provider-network-type vlan network"
Then I want to create two subnets, with different subnet pools. The first one is successfully created, but the second on fails with "BadRequestException: Unknown error"

THe OpenStack version is queens. And it is installed in a Ubuntu 16.04
server.

Thanks
