Re: [Openstack] Filter Scheduler, a complete example
While this blog post doesn't have a simple example, you may find it helpful: https://www.ibm.com/developerworks/mydeveloperworks/blogs/e93514d3-c4f0-4aa0-8844-497f370090f5/entry/openstack_nova_scheduler_and_its_algorithm27?lang=en Michael - Michael Fork Cloud Architect, Emerging Solutions IBM Systems Technology Group From: Christian Parpart tra...@gmail.com To: openstack@lists.launchpad.net, Date: 06/11/2012 11:08 AM Subject:[Openstack] Filter Scheduler, a complete example Sent by:openstack-bounces+mjfork=us.ibm@lists.launchpad.net Hi all, while I am still somewhat new to OpenStack, I was able to successfully deploy a 6-node OpenStack setup with 4 compute nodes, one controller node (yet to be HA'd) and one network node (yet to be HA'd). However, now, that I am that far, I am in need to create a custom filter, due to the companies requirements on what VMs to put on what hardware.

I could not really find anything that helpful yet, and I think it might be a wonderful entry-point for quite a few of us. Is there anyone willing to help us here out a bit?

Re: [Openstack] Filter Scheduler, a complete example
Christian, I have been working on improving filter scheduler and my current blue print is at http://wiki.openstack.org/InstanceTypeExtraSpecsExtension and current code is at https://review.openstack.org/#/c/8089/. If you have any question on my code or filter scheduler, please let me know. Thanks, Joseph (w) 703-248-6160 (c) 571-340-2434 (f) 703-812-3712 3811 N.

Re: [Openstack] Filter Scheduler, a complete example
You may be better off considering a different approach all together. We ran into similar issues involving FISMA constraints and data classification in the past. One 'simple' solution is complete segregation ( not to be confused with isolation ). What we ended up coming up with was to basically deploy one openstack cluster as an operations control cluster then use it to deploy other openstack clusters as a service. If you tie that into live migration you can even move physical machines around between nodes by shutting them off and re-provisioning them as a new node entirely. The primary issue in this approach is network automation. One solution is to deploy gateway systems as a service, but that's a bit of a hack. If you are interested in discussing this further I'd be glad to go into depth in a blog post or something for yah. -Matt On Mon, Jun 11, 2012 at 8:41 AM, Christian Parpart tra...@gmail.com wrote: Hi all, while I am still somewhat new to OpenStack, I was able to successfully deploy a 6-node OpenStack setup with 4 compute nodes, one controller node (yet to be HA'd) and one network node (yet to be HA'd).

Many many thanks, Christian Parpart. ___ Christian: The admin docs have a chapter on scheduling that discusses the filter scheduler: http://docs.openstack.org/essex/openstack-compute/admin/content/ch_scheduling.html It's from a user's point, not a developer, but it does describe what all of the built-in filters do. You should be able to look at the corresponding code and see what they do pretty easily. Check out the nova/scheduler/filters directory which has the implementation of the existing filters: https://github.com/openstack/nova/tree/master/nova/scheduler/filters The simplest filter is the AllHostsFilter, which doesn't filter anything at all: https://github.com/openstack/nova/blob/master/nova/scheduler/filters/all_hosts_filter.py Take care, Lorin -- Lorin Hochstein Lead Architect - Cloud Services Nimbis Services, Inc. www.nimbisservices.com smime.p7s Description: S/MIME cryptographic signature ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
