Hi, I am trying to deploy openstack with tripleO using VMs and nested-KVM for the compute node. This is for test and learning purposes. I am using the Train version and following some tutorials. I prepared my different template files and started the deployment, but I got these errors : *Failed to provision instance fc40457e-4b3c-4402-ae9d-c528f2c2ad30: Asynchronous exception: Node failed to deploy. Exception: Agent API for node 6d3724fc-6f13-4588-bbe5-56bc4f9a4f87 returned HTTP status code 404 with error: Not found: Extension with id iscsi not found. for node* and *Got HTTP 409: {"errors": [{"status": 409, "title": "Conflict", "detail": "There was a conflict when trying to complete your request.\n\n Unable to allocate inventory: Unable to create allocation for 'CUSTOM_BAREMETAL' on resource provider '6d3724fc-6f13-4588-bbe5-56bc4f9a4f87'. The requested amount would exceed the capacity. ",* Could you help understand what those errors mean? I couldn't find anything similar on the net. Thanks in advance. Regards.
