Re: [Openstack] [Openstack-operators] Migrating instances according to load on host

Hi Slawek, there is also Openstack Neat http://openstack-neat.org/ "An extension to OpenStack implementing dynamic consolidation of Virtual Machines (VMs) using live migration" I believe it is exactly what you're looking for. By the way I am currently working on it for my thesis :) Claudio Il

[Openstack] resource_id of host

Hi everyone! I have a question regarding the resource_id of a host. When I create an alarm like this: ceilometer --debug alarm-threshold-create --name cpu_compute1_high --description 'compute1 running hot' \ --meter-name compute.node.cpu.percent --threshold 70.0 --comparison-operator gt

Re: [Openstack] openstack juno in aws with multiple-nodes

Hi Vedsar, I have done in the past the same thing. I have installed openstack on AWS with three node: 1 controller, 1 network, 1 compute. I was able to spawn istances, but they couldn't get their IP without a strange trick: http://lists.openstack.org/pipermail/openstack/2014-September/009514.html

[Openstack] Ceilometer - evaluation interval should be >= collection interval

Hi all, I think there is a problem with the default value of a parameter in ceilometer. In the pipeline.yaml file, the "collection of samples interval" is set to 600 seconds. In the ceilometer.conf file, the "evaluation_interval" is set to to 60 seconds. But there is a hint about that the la

Re: [Openstack] Using DevStack for exploring energy efficient VM placement algorithms

Hi, My master's thesis is about VM consolidation in OpenStack. I have done an extension to OpenStack Neat http://openstack-neat.org/ I have used a cluster for testing, but I think you can also use DevStack in a multi node installation. About temperature, I've found this in the Ceilometer do

Re: [Openstack] [openstack][ceilometer][icehouse]

Hi, can you please tell me more details about what you're doing? You want to do autoscaling based on the number of database connections per instances. What is the event that will trigger an autoscaling action? What do you want to scale? Cheers, Claudio Il 18/03/2015 13:01, Shanker Gudipati ha

Re: [Openstack] Adding New Ceilometer Meters

Hi Girija Sharan, as my master degree thesis I have done a framework for virtual machine migration in OpenStack, which I think it might be useful for what you're realizing. I have extended Ceilometer and OpenStack Neat, a framework for virtual machine consolidation. I had to collect samples of cp

[Openstack] Migration Policies

Hi, Is it possible to create migration policies? My idea was to collect some metrics with Ceilometer, and when a threshold is reached, to trigger the migration of one or more instances. Does Heat or other projects provide support for this? Thanks, Claudio ___
