At my previous employer we did not use namespaces.
This was due to a installation a few years ago on SL6 which did not
I think there are valid reasons to not use namespaces:
* Fewer moving parts == less can potentialy fail
* Troubleshooting is easier due to less places to look / need no
familiarity with namespaces & tools
* If I remember correctly setting up a namespace can get really slow when

As mentioned before I think organizations tend to go with what they already
have.
It is a huge project to switch from x to y if you have a significant amount of
investment/code in x.
Having 2 different configuration management systems within one organization is
no fun either.
I have quite a bit

Hi,
Did anyone implement middleware to push statsd metrics for the OpenStack
components? (swift has this)
E.g. Pushing data about HTTP status codes & request times.
Thx,

P.S.
I know you can also get this info from elastic search if you push your logs
there but that is a bit

Hi,
Is there an easy way to update the quotas for flavors and apply it to existing
instances?
It looks like these settings are tracked in the “instance_extra” table and not
re-read from the flavor when (hard) re-booting the instances.
Since the instance_extra flavor table is a big JSON blob it

Hi,
I had some “interesting” issues in the past with sparse files on xfs with
elasticsearch:

If you pre-allocate your files you should be good.

You might be better of using the RHEV qemu packages
They are more recent (2.3) and have more features compiled into them.

Hi,
Found this thread in the archive so a bit of a late reaction.
We are hitting the same thing so I created a blueprint:

If you guys already found a nice solution to this problem I’d like to hear it :)

Thx for your stories,
I think we are now all doing pretty much the same thing to get around the issue
but it still looks like a very useful feature.
So to share what we (eBay-ECG) are doing:
We also started out with scaling the flavor disksize to either memory or cpu.
(so e.g. large disk == lar

Hello,
Its not really OpenStack related but it depends on your virtualization stack.
Assuming its OpenStack with KVM:

You can specify the IOPS limits in the flavor.
Drawbacks:
* You might end up with a lot of different flavors because of IOPS requirements
* Modifying

Unless it’s a very very ancient unsupported version of centos the virt-io
drivers will be in the kernel package.
Do a lsmod and look for virtio to check if it is loaded.

Hi,
Does anyone know if it is possible to set PCI pass through on a flavor without
also needing to set the alias on the nova API nodes as mentioned here:
https://docs.openstack.org/nova/pike/admin/pci-passthrough.html
E.G you need to set in nova.conf:
[pci]
alias = { "vendor_id":"8086", "product

What do you mean by “clean”?
Contrail will ignore all information in the neutron db.
Any incoming neutron api call will be translated to a contrail-api call.
