Re: [openstack-dev] [nova] Evacuate instance which in server group with affinity policy

Joe, thanks, that's useful feature. But still not sure it's good for this case. Thinking of user's server-group will be deleted by administrator and new server-group created for user by administrator, that sounds confused for user. I'm thinking of the HA case, if there is host failed, the infrastru

Re: [openstack-dev] [nova] Evacuate instance which in server group with affinity policy

This is another great example of a use case in which these blueprints [1, 2] would be handy. They didn’t make the clip line for Kilo, but we’ll try again for L. I personally don’t think the scheduler should have “special case” rules about when/when not to apply affinity policies, as that could

[openstack-dev] [nova] Evacuate instance which in server group with affinity policy

Hi, There is problem when evacuate instance. If the instance is in the server group with affinity policy, the instance can't evacuate out the failed compute node. I know there is soft affinity policy under development, but think of if the instance in server group with hard affinity means no way t
