Yep, it's Queens.

In triple-o land it seems like the config may need to be somewhere like
nova-scheduler.yaml and laid down via a re-deploy.

Or something.

The nova_scheduler runs in a container on a 'controller' host.

No I haven't. Where would be the place to do that? In a nova.conf somewhere
that the nova-scheduler containers on the controller hosts could pick it up?

Just about to deploy for realz with about forty x86 compute nodes, so it
would be really nice to sort this first. :)

Re: [Openstack] unexpected distribution of compute instances in queens

[Mike Carden]

I'm seeing a similar issue in Queens deployed via tripleo.

Two x86 compute nodes and one ppc64le node and host aggregates for virtual
instances and baremetal (x86) instances. Baremetal on x86 is working fine.

All VMs get deployed to compute-0. I can live migrate VMs to compute-1 and
all is well, but I tire of being the 'meatspace scheduler'.

I've looked at the nova.conf in the various nova-xxx containers on the
controllers, but I have failed to discern the root of this issue.

Anyone have a suggestion?

Re: [openstack-dev] [openstack-ansible] Implement rotations for meetings handling

[Mike Carden]

Hi OSA peeps.

I apologise in advance for what may seem like an impertinent question. And
for those playing along at home, I was just getting the hang of
contributing to OSA when last year my employer decided that some of us were
no longer needed, and OpenStack lost quite a few full time employed
contributors.

So my question is... what is the health status of OSA? Is there still a
core of committed contributors? I only check in on OSA code reviews rarely
now, but activity seems a lot less than it was.

Before you answer, imagine that I now work for a moderately large,
potential consumer of OSA.

Is OSA the future, or have other deployment projects made it less relevant?

Re: [openstack-dev] [openstack-ansible][security] Rename openstack-ansible-security role?

[Mike Carden]

I think that a rename is a good idea. Ansible-host-security,
Ansible-host-hardening, Ansible-server-security, etc... all good options.

Re: [openstack-dev] [openstack-ansible] Debugging slow Xenial gate

[Mike Carden]

Major,

I bounced this off my 'distro differences' goto guy, Chris Smart. Here are
his thoughts:

"Run the 14.04 kernel on 16.04 system and re-run the tests to see if it's
kernel related.

If 16.04 userland with 14.04 kernel is as fast as Ubuntu 14.04, then
compare the kernel .config files to see if there were major changes,
like switching out schedulers.

Also, when running the tests on both systems, track cpu usage and number
of threads to see if one has more restrictions than the other.

Check swappiness and also "vmstat 1" to see if you're getting more pages
swapped in and out in 16.04.

I'm assuming that the two virtual machines are identical (CPU type, memory,
threads, virtio, etc)."

I am strongly in favour of images being stored in open formats. Right now
the most widely supported open formats are PNG and SVG. Let's make sure
that as often as possible, we all store non-photographic images in formats
like these.

A possible issue with 'Quay' is that it's pronounced 'Key' which may case
phonetic confusion wherein it's mistaken for a 'K' release.

Then again, I may be biased because I'm an Australian and I live 15km from
'Queanbeyan' (which by the way is never pronounced anything like 'Queen
Bean' as is suggested in the wiki).

Re: [openstack-dev] [Aodh] Ordering Alarm severity on context

Hi Sanjana and welcome to openstack-dev.

Having sent all of us your 'Hitachi1' password, you may want to change
that. :)

In general, fishing for code reviews via the openstack-dev mailing list is
a poor strategy. You may be better served by discovering the preferred
communication channel(s) for the project you are interested in and making
yourself known there.

Someone who knows a lot more than I do about aodh may come along to advise
you of IRC channels and the like.
