[Openstack] scheduler compute node capabilites status update problem
Hi guys, I have a problem with the nova scheduler and the capabilities update period. For Example: If I have a flavor with the extra_specs key / value pair: vcpus_used = '= 2' So, virtual machines should be submitted if the host not more than two vcpus used. However I'm able to start more than two machines, if I do it fast enough. So I have the situation, that for example 5 vms are already running, and I'm still able to submit new machines on that host. If I wait (let's say a minute), the capability vcpus_used will be upgraded, and at that point the filter works. So my question. Is there a possibility to update the host capabilities with every VM submit? PS: I used folsom.

Re: [Openstack] n-api installation problem with devstack (on centos)
Hi Guys, Now I found the solution for my problem: n-api installation/start (via devstack) failed on centos 6.x with the error message below The problem is the old python-paste version of centos. So if you get this error, just remove python-paste with: yum remove python-paste python-paste-deploy python-paste-script and install the new one via pip: pip install --upgrade paste PasteDeploy PasteScript in the last step you have to remove the package names (paste, paste-deploy, paste-script) in devstack (./files/rpms/*) , because stack.sh will install this package with the next run. = -Original Message- From: openstack-bounces+mauch=kit@lists.launchpad.net [mailto:openstack-bounces+mauch=kit@lists.launchpad.net] On Behalf Of Mauch, Viktor (SCC) Sent: Monday, September 24, 2012 3:39 PM To: openstack Subject: [Openstack] n-api installation problem with devstack (on centos) Hi, I have a problem with the installation of n-api (via devstack) on CentOS 6.3.

Or being more specific,
How can a add key/value pairs to a compute node???
So I can check the extra_specs data with the key/value paris of the compute
node?

Just one more noob question.
Is it normal that If I set a set key/value pair let's say
{my_special_key:my_special_value} to an existing flavor, that the
scheduler failed to find a host for an instance of this flavor.

The simplest way would be to create key/value pairs for flavor types
(instance types).
This information would be associated in a separate table in nova db
(instance_type_extra_specs) and would go along with the instance type.
Once it is in the database, you can use this information to customize all
kinds of things like the nova scheduler, additional data that can be passed
to the instance at the time of the creation. This is the high level
overview. If you search the mailing list archives you will find some
additional discussion about this topic.

Re: [Openstack] how to use extra_specs??
Yes sure,
But in this example you use an existing key free_ram_rmb?! Ist that right?
What I want to do is to create my own key value paris for compute nodes (who
can I do that) and for the extra_specs variable of the flavors

You can also use the cli, does the job too
nova boot --flavor 1 --image 1f3fbdde-4c8a-4b3b-9cf1-a3b9fd0f1d9e --key_name

[Openstack] devstack multi-node tutorial fails
Hi, I just want so say, that some days ago the stack.sh script hast been changed concerning the rabbit server installation. The current description for multi node tutorial (http://devstack.org/guides/multinode-lab.html) will fail. At the moment it is necessary to install the rabbit service on the compute hosts TOO (but of course with the IP from the master node)!! e.g.: ENABLED_SERVICES=n-cpu,n-net,g-api,rabbit RABBIT_HOST=$MASTERNODE RABBIT_PASSWORD=pass Otherwise the compute node tries to find a rabbit-mq server on localhost! There are also some other wrong details in the multi-node toturial. It must be: RABBIT_PASSWORD and MYSQL_PASSWORD instead of MYSQL_PASS und RABBIT_PASS Und the parameter MULTI_HOST=1 has to be change to MULTI_HOST=True (and should only be available on the master node, as I understand it right).
