[happy idea]

"Live Migration failure: not all arguments converted during string
formatting"
You need to find the error code location, and log the stacktrace.

Re: [Openstack] Havana-3 development milestone available

[Martinx - ジェームズ]

Hi!

I'm seeing that `Ubuntu Cloud Archive' for Havana is outdated... Still not
H3...

How can I test it today? Is there any PPA with most recent package versions
available? Or maybe, is it ready for tests only for Saucy?

Thanks!

That does seem to be the case, at least the symptoms match.

Based on the comments you made on that bug is sounds like increasing
"agent_down_time" should help with this?  I had already increased from the
default 5sec to 20sec going to try a full minute and see if the incidence
of problems decreases.

Thanks,

Re: [Openstack] [Quantum] dhcp-agent stops updating dnsmasq

[Édouard Thuleau]

Hi Jon,

Effectively, a bug [1] was identified. When DHCP agent is down because its
overloaded, Neutron agent will not send update to that agent and doesn't
raise the problem.
I submitted small patch to a warning log but I abandoned it to propose
another one (not yet finish) which will raise an exception and destroy the
created port.

+1. Very succinct, and it does remove ambiguity. Giuseppe, feel free to update 
the wiki to reflect this, and help remove ambiguity in other areas. Thank you

Re: [Openstack] [Grizzly] Unable to reboot instance after Migrate

[Guilherme Russi]

Hello Happy,

 I've my NFS configuration again, but I keep getting this error on my
compute's logs:

Live Migration failure: not all arguments converted during string formatting

I don't know if it's a problem with my nova or my libvirt, my compute nodes
connect to another NFS server that is not my controller node, would may be
it?

Thank you.

The misleading thing to me is that it sounds like I only get one database
user. As in, it creates an instance, spins up MySQL, and creates a single
tenant inside the database.

It also is ambiguous enough that one might miss the significance of the
dash and hear that it creates a single, tenant-database.

As nice as succinct descriptions are, it may be worth clarifying all of
the objects in the sentence.

Perhaps: "Trove is designed to support a multi-user database for a single
OpenStack tenant within a Nova instance."

[Openstack] OpenStack User Survey - Round 2

[Tom Fifield]

Hi all,

You might remember before the April Summit we ran a survey of OpenStack
deployers. We’re doing it again, and we need your help!

If your organization is running an OpenStack deployment, please
participate in the survey [http://www.openstack.org/user-survey]. If you
already completed the survey in April, you can simply log back in to
update your deployment details and answer a few new questions.

If you are a contributor, please help us spread the word. We're trying
to gather as much real-world deployment data as possible to share back
with you.

The information provided is confidential and will only be presented in
aggregate unless the user consents to making it public.
The deadline to complete the survey and be part of the next report is
September 30 at 23:00 UTC.

Questions? Check out the FAQ [https://www.openstack.org/user-survey/faq]
or feel free to contact me [t...@openstack.org].


Thanks for your help!

Regards,


Tom

Re: [Openstack] [TROVE] database instance creation

[Giuseppe Galeota]

Dear all,
reading the TROVE's
Doc
 I see that "The trove-taskmanager service does the heavy lifting as far as
provisioning instances, managing the lifecycle of instances, and performing
operations on the *Database instance*".

So, once an instance was created, how does an application deployed in the
cloud platform (IaaS or PaaS level) perform CRUD operation on that database
instance? Maybe, does the trove-taskmanager release an endpoint on which
create a DBMS connection?

What exactly is misleading about that? Don't get me wrong, I've been working on 
trove for a long time, so to me, the definition makes sense. But if its 
misleading for newcomers, lets work to make it sound less so!

Also, removing openstack-dev list. This is more general question stuff that's

[Openstack] [Quantum] dhcp-agent stops updating dnsmasq

[Jonathan Proulx]

Hi All,

I'm running Grizzly on Ubuntu 12.04 and using quantum ovs.

Periodically it seems the quantum-dhcp-agent stops informing dnsmasq when
new ports are created.

looking at the instance info from nova or the related port information in
quantum the MAC address to IP mapping shows up correctly.

The dnsmasq 'host' file has no record of either and while dnsmasq logs show
requests from the MAC(s) in question it also logs "no ip available"

Existing registrations renew properly  and the quantum-dhcp-agent continues
to run with nothing logged.  Restarting quantum-dhcp-agentget things back
to normal, but this is happening multiple times a day and my only current
means of detection is user complaints.

currently there are 365 active ports on the default network with a
lease_time of 30min (default is 2min). There are a few project networks
with a small number of active ports, it is unclear if these have the same
issues do to small sample size.

I'm thinking of pushing the leas_time further out maybe to a few hours, but
it's unclear to me if that would help.

-Jon

Re: [Openstack] [TROVE] database instance creation

[Daniel Salinas]

Trove allows you to deploy a single vm with 1 server instance of whichever
service supported.  So for example, if you were to deploy a mysql instance,
you would have 1 vm with 1 mysql instance running on it.  You can put as
many databases on that one server instance as you would like with as many
database users as you would like.

[Giuseppe Galeota]

So, I think that "Trove is designed to support a *single-tenant *database
within a Nova instance" is a misleading definition. What do you think?

[Openstack] [TROVE] database instance creation

[Giuseppe Galeota]

Dear all,
reading the TROVE's
DocI see
that Trove is designed to support a single-tenant database within a
Nova instance.

What does means this?

Does it mean that Trove creates a single VM instance in which a single
database instance is created?

Does it mean that Trove creates a single VM instance in which a more
database instances of a single tenant are created ?

Thank you,
Giuseppe

[Openstack] Load balancing traffic to instances

Hi,

i have a setup based on CentOS 6.4, quantum with vlan and have two
(potentially more) guests on one of the subnets.

What is the *simplest way* to balance HTTP (potentially other protocols)
incoming traffic to the instances?

Thanks,

Do you mean design summit sessions, or summit (conference) presentations
