I could re-create the same with the latest devstack and long hostname
stack@myci:~/devstack$ hostname
myci.home.org
stack@myci:~/devstack$ sudo ovs-vsctl list open_vswitch
_uuid : 3859f81a-2f37-456c-b3da-bb068f30310f

ovs_version : "2.13.5"

A fix for this config:
stack@myci:~/devstack$ sudo ovs-vsctl set open_vswitch . external-
ids:hostname='myci.home.org'
After that everything works. So this is rather devstack bug

Title:
Neutron with OVN fails to bind port if hostname has dots
Status in devstack:
Confirmed
Bug description:
If the hostname has dots, as in for example "devstack.localdomain",
when trying to create an instance, Neutron will fail with "Failed to
bind port".
Reproduced with the latest DevStack from master on top of Ubuntu
Server 20.04.3 LTS with latest packages installed. Minimal
installation, no additional packages installed (only removed
python3-simplejson and python3-pyasn1-modules due to recent issues
with those packages[1]).
I find this weird, because afaik TripleO uses FQDNs, so in theory
Neutron with OVN should break their CI (although I'm not sure if they
use OVN or Open vSwitch). I'm still not sure if this is on my end or
not, but I was able to reproduce this consistently, trying different
hostnames, trying the most minimal local.conf possible (setting only
passwords), so I decided to report it as a bug.
Steps to reproduce:
1. Set the system's hostname to something with at least one dot
2. Deploy DevStack
3. Create instance on any network
4. Inspect devstack@q-svc.service to see the error
Expected output:
Instance is created successfully
Actual output:
Instance enters error state and devstack@q-svc.service reports this:

Version:
DevStack from master
Ubuntu Server 20.04.3 LTS
OVN mechanism driver
Environment (local.conf): https://paste.openstack.org/show/809316/
Perceived severity: low
