Hello everyone,
When I start the instance in the provider network, I come into a problem: the instance started slowly and said "further output written to /dev/ttyS0", and it can't get access to the Internet.
Has anybody experienced the same problems? Do you have any suggestions on what could be the cause of these problems? Thanks in advance!

AMQP server on controller:5672is unreachable means that the DHCP agent is unable to communicate with other parts of Neutron via the message bus. I guess you need to replacecontrollerwith an IP address or a different hostname in the DHCP agent config file.
