Thanks for your fast answer.
I tried these options on all nodes, but it didn't seems to work
(connection refused again).
I have googled a bit more, and I saw I can load nova-api on each compute
nodes, with only the metadata service (--enabled_apis=metadata).
This setup works well and enable HA for api so it can be a good solution.
Thanks for the help and sorry for not googling enough before asking ;)
And about nova.conf format, should I prefix options or not ?
