Hello. I was upgrade our ovirt-engine from 4.3 to latest 4.4.3.12. Seems all flawless, except our storage domain (Cinder). Currently our clusters can't start VM, create Disks, resize disks, etc. Only migration works. The root cause: ovirt missing project_id in API call: ovirt 4.3 call: 17910:2020-12-02 20:43:32.087 1949 INFO eventlet.wsgi.server [req-7267b4fd-9659-4380-9297-4582ece3fe23 - - - - -] 192.168.101.10 "POST /v2/07f5bf3f6dc64b85988c3779654e175e/volumes/e3df2f84-2206-4165-9001-bcace8613315/action HTTP/1.1" status: 200  len: 777 time: 0.4810839 ovirt 4.4 call: 2020-12-05 14:09:24.155 2031 INFO eventlet.wsgi.server [req-71b47b34-8ed7-410a-812f-8f662f9f4037 - - - - -] 192.168.101.10 "POST /v2/volumes/e3df2f84-2206-4165-9001-bcace8613315/action HTTP/1.1" status: 404  len: 333 time: 0.2505009 provider configuration in engine database: engine=# select * from providers where name='cinder_ceph_backened'; -[ RECORD 1 ]---------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- id                    | 9c5800e6-5a88-403a-9c57-a501714fe816 name                  | cinder_ceph_backened description           | OpenStack Cinder with Ceph Backend url                   | http://192.168.101.20:8776 provider_type         | OPENSTACK_VOLUME auth_required         | t auth_username         | admin auth_password         | OUDZtXsI4eOT69UKYI2DNqTFmN3c08XNAbbi3PQHq2Np319yURcIjhOJ81lKUo+T+pa/e6d5XUbPZmwulCK21fU5UrY2uJBSg8GXaVH23os7BmZzx+7V0V82LLBFYWUAAACeXY0hu9UGgQiMd0L7wPS0hU23iSib/BWnCcxY6h4ooQ0/pfKNZ10so5tKin/mAgMHNmX2YtqiYaQgZTYpDcIf9JnfqsiJKUW3xekPzTJQCIUEDbX/1Jpp5sJCW5aFHDSiy1I9CU/etAcqrzf6JMN8Mfn6X4VZjXqrg4YQ+QD6TiTwOAS7u7oJwCYopdRHvGNspc2YbPykN62NgFWwmg== _create_date          | 2017-04-05 19:30:57.045699+07 _update_date          | 2020-12-05 13:27:31.320646+07 custom_properties     | tenant_name           | admin plugin_type           | auth_url              | http://192.168.101.20:5000/v2.0 additional_properties | read_only             | f is_unmanaged          | f auto_sync             | f user_domain_name      | project_name          | project_domain_name   | Now we miss some field or bug in code where project_id (admin = 07f5bf3f6dc64b85988c3779654e175e) is not concat to uri?
