Public bug reported:
I ran into a problem when the network inside the newly created VM is not
working.
* Pre-conditions:
- the neutron ovs agent has not yet seen any ports from the VM network;
- any other bridge (except for the network in which the VM is created) is
recreated on the node.

I ran into a problem when L3 agent fails to process the external network change
on the router and was hitting the retry limit.
I'm using a devstack deployment over the master branch.

I run into a problem when unicast RA messages are not accepted by openflow
rules.
In my configuration I'm using radvd daemon to send RA messages in my IPv6
network.
Here is a config of radvd with `clients` dirrective to turn off multicast
messages:

I run into a problem when neutron dhcp-agent is still replying to the old
address confirmation.
Simple steps to reproduce:
- create a port with IPv6 address in dhcpv6-stateful subnet
- create a VM with cloud-init inside
- change the IPv6 port address
- reboot the VM

I can't find a way to set up VPN quotas using the CLI tools: neither the
openstack CLI nor deprecated neutron CLI has this feature.
I can only update VPN quotas using a direct API request (e.g. via curl).
And can only list VPN quotas using neutron CLI tool.

We got an issue when keepalived stops to be running after update MTU on the
internal network of the DVR-HA router.
It turned out that the keepalived config has an interface from qrouter-ns
although the keepalived process itself is running in snat-ns.

Public bug reported:
We discovered that if the nova metadata service is down, then the
neutron metadata service starts printing stack traces with a 500 HTTP
code to the user.
Demo on a newly installed devstack
$ systemctl stop devstack@n-api-meta.service
Then inside a VM:
$ curl http://169.254
Public bug reported:
When trying to GET a non-existent metadata key within the VM, like
'/latest/meta-data/hostname/abc', the Nova metadata service responses
with a 500 HTTP status code:

I encounter a very strange behavior when I try to add and delete the

Public bug reported:
Our customer reported an issue where he does not understand what is
wrong with the DHCP service.
As it turned out, during the management of subnet allocation pools, he
accidentally deleted the allocation pool (thinking that the entire range

Then he reset (off
Public bug reported:
During the processing of a router by the L3 agent in
`agent_mode={dvr|dvr_snat}`, we create a floatingip_agent_gateway port.
The code in the L3-agent [0] and the neutron-server [1] assumes that there
should be only one such port per L3-agent per network. However, this is no

I ran into a problem when the list of networks filtered by segment ID does not

An important condition is the parallel removal of another network.

We are testing the network availability of VMs in case of HA events.
And we run into a problem where aborting live migration of a VM can break
communication with that VM in the future at the OVS rules level.
The fault of the wrong OVS rules is the stuck INACTIVE port binding

We ran into a problem in our openstack cluster, when traffic does not go

We had an update from one version of the Openstack to another and by chance we

Public bug reported:
The nova-api raises exception on attempt to get VMs sorted by i.e.

- try to list servers sorted by sort_key=task_state

I found that neutron-server does not wait for successful port provisioning from
the dhcp agent in the case of VM creation. DHCP entity is not added into
