Found this nova bug[0] and another talk in openstack-dev[1].

The question is: why this happens now and then? sometimes the gate is OK. and 
others not.

Recently, centos 7.3 is release. libvirt is upgrade to 2.0 version.

But in kolla's gate. the nova_libvirt container failed now and then.

What i found is:

1. Simple start nova_libvirt container is OK.
2. When launching a new instance, libvirt is killed without any logs in 
libvirtd.log file.
3. in system messages log, i found following line.

Dec 29 00:41:24 localhost kernel: libvirtd[24340]: segfault at 8 ip

No idea why and how this happen. Any idea on this?

[openstack-dev] [nova] Consistency in versioned notification payloads

[Matt Riedemann]

While reviewing patches today to add versioned notifications for CRUD 
operations on aggregates and flavors I've come across some inconsistency.


The existing non-versioned notification for aggregate.delete just sends 
the aggregate id, but the versioned notification is sending the whole 
aggregate object in the payload:


https://review.openstack.org/#/c/394512/9/doc/notification_samples/aggregate-delete-end.json

But with the flavor-delete versioned notification, it's just sending the 
flavorid:


https://review.openstack.org/#/c/398171/16/doc/notification_samples/flavor-delete.json

So which should we be doing? Either way you can correlate the id on the 
resource in the notification back to the full record if needed, but 
should we be sending the full object in the versioned notification 
payload while we have it? I don't much care either way which we do as 
long as we're consistent.

Thanks,

Matt Riedemann

[openstack-dev] [keystone] Feedback for upcoming user survey questionnaire

[Steve Martinelli]

We have the opportunity to ask one question on the upcoming user survey and
we get to decide the audience to which we serve the question.



Our audience options are: USING, TESTING, or INTERESTED in Keystone (I
think we should aim for USING or TESTING)



The question can take one of several forms; multiple choice (select one or
more), or short answer.



Post your suggestions here or email them to me privately ASAP so I can
respond to the team assembling the survey in sufficient time.

Re: [openstack-dev] [neutron][ml2] Mechanism drivers ! OpenvSwich or Linuxbridge or both of them?

[Sławek Kapłoński]

Hello,

I don't know what is hierarchical port binding but about mechanism
drivers, You should use this mechanism driver which L2 agent You are
using on compute/network nodes. If You have OVS L2 agent then You should
have enabled openvswitch mechanism driver.
In general both of those drivers are doing similar work on
neutron-server side because they are checking if proper agent type is
working on host and if other conditions required to bind port are valid.
Mechanism drivers can have also some additional informations about
backend driver, e.g. there is info about supported QoS rule types for
each backend driver (OVS, Linuxbridge and SR-IOV).

BTW. IMHO You should send such questions to openst...@lists.openstack.org

[Openstack-operators] LBaaS V2 on multi-node Neutron Liberty

[William Josefsson]

Hi everyone, I need some advice on installing LBaaS on my Liberty
(CentOS7) deployment. I have a multi host deployment with 2 Networking
nodes running all my agents (L3, dhcp, .. )

I have reviewed this [1] documentation, and I notice there is LBaaS
agent based V2, which is the current version, should I install this
[2] 'yum install openstack-neutron-lbaas' package only, or should I
install 'yum install haproxy openstack-neutron-lbaas' on my network
nodes?

I have two Networking nodes, should proceed and install the agent the
same way on both, and then just verify with neutron agent-list?

This [1] Neutron documentation also mentions: "neutron-db-manage
--service lbaas upgrade head".
Can anyone please share what kind of modifications will occur to my DB
and if it will affect any of my existing data with networks, subnets,
ports etc in a harmful way, or is this a safe command to run?

thx will!

[openstack-dev] [ironic] [nova] Ironic virt driver resources reporting

[Vladyslav Drok]

Hi all!

There is a long standing problem of resources reporting in ironic virt
driver. It's described in a couple of bugs I've found - [0], [1]. Switching
to placement API will make things better, but still there are some problems
there. For example, there are cases when ironic needs to say "this node is
not available", and it reports the vcpus=memory_mb=local_gb as 0 in this
case. Placement API does not allow 0s, so in [2] it is proposed to remove
inventory records in this case.

But the whole logic here [3] seems not that obvious to me, so I'd like to
discuss when do we need to report 0s to placement API. I'm thinking about
the following (copy-pasted from my comment on [2]):


   - If there is an instance_uuid on the node, no matter what
   provision/power state it's in, consider the resources as used. In case it's
   an orphan, an admin will need to take some manual action anyway.
   - If there is no instance_uuid and a node is in cleaning/clean wait
   after tear down, it is a part of normal node lifecycle, report all
   resources as used. This means we need a way to determine if it's a manual
   or automated clean.
   - If there is no instance_uuid, and a node:
  - has a bad power state or
  - is in maintenance
  - or actually in any other case, consider it unavailable, report
  available resources = used resources = 0. Provision state does not matter
  in this logic, all cases that we wanted to take into account are
described
  in the first two bullets.


Any thoughts?

[openstack-dev] [neutron][ml2] Mechanism drivers ! OpenvSwich or Linuxbridge or both of them?

[zhi]

Hi, all

First of all. Happy New year for everyone!

I have a question about mechanism drivers when using ML2 driver.

When should I use openvswitch mechanism driver ?

When should I use linuxbridge mechanism driver ?

And, when should I use openvswitch and linuxbridge mechanism drivers ?

In my opinion, ML2 driver has supported hierarchical port binding. By using
hierarchical port binding,
neutron will know every binding info in network topology, isn't it? If yes,
where I can found the every binding info. And what the relationship between
hierarchical port binding and mechanism drivers?


Hope for your reply.

Thanks

[Openstack] Glance, Cinder and several upload options?

[Florian Rommel]

Hi, so I managed to get Cinder to work with nfs, ceph and SMBFS creating 
a multi-tier architecture. The permissions on the smbfs server are still 
a small problem but when inherited and automatically changed, it works 
very well.. also VERY fast.


On to the next issue.
I have glance images currently on ceph and thats ok but every time I 
deploy a volume to the smb tier, it downloads the image the control node 
(why?!?!?) and then creates the volume into smb or nfs .

Its very very very slow.
I tried to make a glance image-volume but I keep getting the following 
error.


ERROR glance.common.wsgi AttributeError: 'Store' object has no attribute 
'volume_id'


The default glance store is now cinder ( was rbd), all the cinder 
options are enabled and yet its a no go.


Is there something else I need to change?  The volume does exist on 
cinder and if i change the name of it, i get the url was malformed so it 
seems it finds the file but somehow it cannot add the volume id into the 
metadata?


this is what i run:
openstack image create --disk-format raw --container-format bare 
Linux-SMBFSTEST

which returns to me a uuid of: b97704ba-7b22-493d-a3bb-4ce597c9ddc2
and then I run
glance location-add --url cinder://e080103c-049e-4d91-9a3c-5322a505e5a4 
b97704ba-7b22-493d-a3bb-4ce597c9ddc2


the cinder volume being volume-e080103c-049e-4d91-9a3c-5322a505e5a4 and 
fully accessible with no permission restriction..


any help? anyone?


Thank you already

Re: [Openstack-operators] [nova] Live migration performance tests on 100 compute nodes

[Koniszewski, Pawel]

Matt,

This was a bandwidth issue. Nova kept being connected to the broker, but it 
started to timeout on RPC messages, e.g., we lost some RPC messages triggering 
post live migration steps which are there to update nova DB to reflect new host 
of an instance.

The good workaround for this issue is to slightly limit bandwidth used for live 
migrations through nova.conf [1], live_migration_bandwidth config option in 
[libvirt] section. By default it is set to 0, so, basically, it is unlimited. 
Also please be aware that we changed default live migration configuration in 
OpenStack Newton and tunneling is now off by default (live_migration_tunnelled 
in [libvirt] section is set to False) due to huge performance impact.

Hello everyone,

We made a research to see how live migration performance varies between 
different configurations, especially we aimed to test tunneled vs non-tunneled 
live migrations. To test live migration we simulated a case of 0-day patching 
of 100 compute nodes (including reboot) with workloads that are close to the 
real world workloads. All the results were published [1] along with environment 
configuration and how we built test framework. Hope you find this useful.

Thanks for the write-up. I'm curious about your RabbitMQ connection failures. 
Was it nova-compute failing to connect? Was it a bandwidth or heartbeat issue?
