Expected Behavior

What should have happened?

The Terraform Openstack Provider should have realized that the volume type of volume defined in block_device section has multiattach option enabled and choose correct microversion for compute endpoint (set X-Openstack-Nova-Api-Version header).

or

There should be a ability do define microversion for selected service endpoints.

Actual Behavior

What actually happened?

The Terraform Openstack Provider sends the default microsversion for the compute endpoint (does not set the X-Openstack-Nova-Api-Version header) and the operation fails.

openstack_compute_instance_v2.bastion01: Creating...

Error: Error creating OpenStack server: Bad request with: [POST https://my-cloud:13774/v2.1/servers], error message: {"badRequest": {"code": 400, "message": "Multiattach volumes are only supported starting with compute API version 2.60."}}

  13: resource "openstack_compute_instance_v2" "bastion01" {

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. Create volume type with multiattach option enabled

$ cinder type-create gp-ceph-nolimit
$ cinder type-key gp-ceph-nolimit set multiattach="<is> True"

2. Create volume and instance based on this volume type (as in 'Terraform Configuration Files' section above)
