Hi Hervé,

We can consistently reproduce the MessageUndelivered error in nova-compute when trying to attach 7 cinder volumes right after a VM is created, all via a heat template.

Maybe you can give use case a try.

The way to get rid of the error is: (1) Set direct_mandatory_flag to 0 for nova-compute, and use a very big rpc_response_timeout (240) in nova_api.

The same heat template runs OK in Rocky, we are also looking at why it fails now in Train.
