Re: [openstack-dev] [nova] Automatic Evacuation

Are there any resources available or proven examples on using external tools which call nova evacuate? For example use a monitoring tool to detect node failure and let the monitoring tool call evacuate on the instances which were running on the failed compute node. On Mon, Mar 3, 2014 at 11:28

there are a lot of rules for HA or LB, so I think it might be a better idea to scope the framework and leave the policy as plugins. On Mon, Mar 3, 2014 at 10:30 PM, Andrew Laski andrew.la...@rackspace.comwrote: On 03/01/14 at 07:24am, Jay Lau wrote: Hey, Sorry to bring this up again. There

Yes, it would be great if we can have a simple framework for future run time policy plugins. ;-) 2014-03-03 23:12 GMT+08:00 laserjetyang laserjety...@gmail.com: there are a lot of rules for HA or LB, so I think it might be a better idea to scope the framework and leave the policy as plugins.

Hi, Would like to know if there's any interest on having 'automatic evacuation' feature when a compute node goes down. I found 3 bps related to this topic: [1] Adding a periodic task and using ServiceGroup API for compute-node status [2] Using ceilometer to trigger the evacuate api.

Im also curious about that. I think it is proper that ceilometer should have the role of Mornitoring vm. Nova just opens auto-evacuate API, when a trigger calls the API nova calls like shelve api for the vm re-spawn. What do you think of this? 2014. 2. 21. 오전 7:13에 Costantino, Leandro I

Hi, If I am not mistaken Mistral team listed Live migration as a potential use case for workflow engine. There is no much details though. https://wiki.openstack.org/wiki/Mistral#Live_migration As I know Mistral plan to implement generic event handling mechanism when one can bind any kind of
