Do several times I can bind floating ip to instance and go into the console of instance.
I want to go into the instance's console, I refresh several times I can go into it.
If I want to associate floating ip to a instance, I do sereral times only can success.
Why I should do so many times?
Just wanted to know which tool you used to deploy Openstack, If its Juju, Can you run ' juju config nova-cloud-controller ' and paste the output. Also please show ' juju status '
set up the HA openstack by myself manually.
My guess is that some of your controllers are not correctly configured. You try a few times until HA-Proxy (that's what you are using, right?) sends your request to a controller that works.
Look for errors in the Nova log files. Or test this by selectively removing controllers from the cluster.
