Re: [Openstack] DHCP problem in grizzly

[Thomas Kärgel]

Hi,

Unfortunately i was bussy with some other topics regarding the current
project im involved in, but I'm still trying to solve this issue.

A shot status update regarding dnsmasq issues we discovered:
-dnsmasq developers don't see the possibility that the behaviour we are
experiencing is caused by dnsmasq.
-I had some interesting discussions with some of the developers at my
office regarding the hostsfile and it's usage. We concluded with the
assumption that this behaviour may be caused by an old file handle. So
that dnsmasq is still reading old data from disc and not the updated
hostsfile.
-The next steps will be to check the filesystem handle of the hostfile
during runtime. One Option for a solution is to try to do an  filesystem
sync bevor sighuping dnsmasq. Another option is to change the filesystem
on which the hostfile resides.

I hope with information we're able to hunt this problem down soon. I
would appreciate any help.

Best regards

Thomas

[Openstack] How to query healthnmon?

[Jobin Raju George]

Hey stackers!

I am trying to use healthnmon to get meters regarding CPU/Memory
utilization. But I can't find any documentation as to how to query
healthnmon to get these data. I would appreciate if someone would point me
to a link for the same or give an example how I could query healthnmon. I
have referred to this link but it isn't very helpful:


   - Utilization data 


I have a controller node and a compute node on two different hosts(both on
Ubuntu 12.04). I couldn't get ceilometer to fetch these data for me and I
read healthnmon is meant for this purpose. Please correct me if I am wrong.

[Openstack] How to Setup Networking for single node installation with 3 NICs

[Jake G.]

Hi all,

I just finished installing Grizzly on one node (CentOS 6.4) via the RDO method. 
I have 3 NICs on the single node installation and would like to configure 
Openstack networking in the following way:

NIC1 - Management & Storage Network 192.168.1.0/32 
NIC2 - Public Network 45.65.110.0/32 
NIC3 - Private Network 10.10.4.0/32 (These are fake IP ranges for my example)

How can I configure Openstack this way? What part do I need to modify? 
Documentation links would be very helpful.
I am having a really hard time putting each part together.Thank you for your 
help!

Re: [Openstack] Keystone store-quota-data blueprint

[Everett Toews]

This topic came up at the last summit in Portland at [1] and [2].

Yehia and another colleague of his from HP had a design that was discussed and 
it seemed like they were going to start work on it. Another developer from CERN 
expressed interest too. I'm not sure if anything ever really got started on it.

I think you'll want to wait until Dolph gets back (next week?) before doing any 
major work on it. Ask him before moving forward.

[Openstack] [Nova] CPU Scalling, Quota for Disk I/O

[Bruno Oliveira ~lychinus]

Hello Stackers,

Today morning I saw an interesting question regarding CPU Scaling
in the list, which got me to ask the following:

Currently (or in the roadmap) do we have any feature on Nova
(regardless of the hypervisor underneath) to set maximum disk I/O
throughput a VM can have ?

I mean, let's say we have hundreds of VMs under the same host as
in production, and for some reason we're lacking performance due to
one (or a few of them) being too hungry/greedy for disk reads/writes.

Question 1) Is there a way we can set quotas for disk I/O for a (group of)
instances ? Like: for this one (or this group), don't exceed the threshold
of 50 MB/seg

Question 2) Also, do we have anything like vertical scalling ?
I mean, like defining CPU and Memory Balloons as extra resources
that a set of VMs can make use of (temporarily), if they're demanding to ?

Note: I've seen some of the videos of "Heat" talking about increasing
horizontally  the number of instances behind a load balancer to attend
an increasing number of user requests, for instances...

Thank you so much.

Re: [Openstack] [Grizzly][Quantum] Fail scheduling network

[Arindam Choudhury]

Hi,

Having the same problem.

Subject: [Openstack] [Grizzly][Quantum] Fail scheduling network

Hi everyone,

I am getting this warning (which seems more like an error) when trying to 
launch instances: á
/var/log/quantum/server.log:2013-06-24 09:34:03 áWARNING 
[quantum.db.agentschedulers_db] Fail scheduling network {'status': u'ACTIVE',

u'7a753d4b-b4dc-423a-98c2-79a1cbeb3d15', 'provider:segmentation_id': 2L}



The instance launches (on a different node) and seems to work correctly. áI 
have gone over my quantum configuration on both nodes and all the IP's and 
hostnames seem to have been set correctly (I can post configs if handy).

Here is my setup: áI have three "all-in-one nodes" (test1,test2,test3) that 
each run all of the services (except l3-agent... áthat only runs on one node at 
a time). áThe APIs, novnc-proxy, and mysql (actually Percona/Galera Cluster) 
are load balanced with haproxy. áAll services have their APIs bound to the 
internal IP. áhaproxy is bound to a VIP that can move around with pacemaker.

In the example above a request comes into haproxy on test2. áquantum-server 
spits out the warning above on test2, test1 launches the instance and seems to 
work fine (without any warnings or errors). á áOddly, test3 never seems to even 
try to launch any instances. á Here is a list of my nova services and quantum 
agents:

Dear List,


i am trying to retrieve measurements from swift via ceilometer.
ceilometer stores its measurements in db and so. looks good.


The ceilometer V2 Web API is expecting resource_id as UUID value, for
example. I can not find a UUID anywere. When listing resources (GET
/v2/resources/) the result contains a lot of ids for various things but
non in UUID format.

What am i doing wrong?


Thank you and nice day.

I read that from Havana, Ceilometer and Healthnmon will be merged, it's

There are several ways you could approach this problem, but I'll mention
the AutoScaling capability provided by heat, as it does exactly what you
want AFAICT.

We provide orchestration capabilities which allow you to spin up groups of
instances, e.g running web server applications, and balance requests via
another instance running a simple haproxy based loadbalancer (so you don't
need an actual physical loadbalancer appliance).

You can use the AutoScaling functionality without any loadbalancer resource
if you wish, such as in the OpenShift demo linked below (where the broker
node is doing the load balancing)

The trigger for scaling out can either be manual (using the InstanceGroup
resource combined with stack updates), or automatic (using the
AutoScalingGroup resource combined with alarms.

There are example templates in the heat-templates repository:

https://github.com/openstack/heat-templates/blob/master/cfn/AutoScalingMultiAZSample.yaml

Here are some demo videos which describe/demonstrate this feature in more 
detail:

http://www.youtube.com/watch?v=9lLSZi6njq4

http://www.youtube.com/watch?v=nEzK-2lsEVg&feature=youtu.be&t=34m35s

Do you, or any of the Redhat people, know if the Red Hat 6 kernel is also
