I am using openstack latest victoria release on ubuntu 20.04. The instance is launched from horizon and storage types are created.
From UI,
boot source is: IMAGE Create New Volume: Yes Size: 5 Below is the output that I have set default volume type in cinder.conf root@storage:/etc/cinder# grep default_volume_type cinder.conf default_volume_type = lvm_backed However from openstack cli I have created a volume from image in lvm_backend storage type and booted a instance from it. It goes successful. I haven't set any property in image. Below is the image output. +-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | checksum | ab8436743c2a55b25615afa265631584 | | container_format | bare | | created_at | 2020-12-17T08:58:56Z | | disk_format | qcow2 | | file | /v2/images/1024317b-0db6-418c-bc39-de9b61d8ce59/file | | id | 1024317b-0db6-418c-bc39-de9b61d8ce59 | | min_disk | 0 | | min_ram | 0 | | name | Ubuntu2004-Official | | owner | 890eb2b7d1b8488aa88de7c34d08817a | | properties | os_distro='ubuntu20.04', os_hash_algo='sha512', os_hash_value='e8c8eb68bfca0aa3f165750d7b913f51cf7ded73e6f51f4c59d08b8788ad4e570f04e92318fd52ffea396ee55e2771d3def475c5b52992c6b43eb591d2a288e2', os_hidden='False', owner_specified.openstack.md5='', owner_specified.openstack.object='images/Ubuntu2004-Official', owner_specified.openstack.sha256='' | | protected | False | | schema | /v2/schemas/image | | size | 547815424 | | status | active | | tags | | | updated_at | 2021-02-09T06:29:57Z | | virtual_size | 2361393152 | | visibility | public | Look like horizon is prefering __DEFAULT__ storage type while creating an instance from cinder backed volume.

Hi,
I am creating nova instance with cinder backed iscsi storage. I have created multiple storage types. But my launched instance from image use storage type __DEFAULT__ for flavor's root volume.
Is the instance launched via horizon or CLI and if CLI which command is used?
I have changed default_volume_type to mystoragetype in cinder.conf but instances root volume still goes in __DEFAULT__ storage type.
This should not happen since default_volume_type has a higher preference than the __DEFAULT__ type
However new volume creation in mystoragetype is successful.
Need help, how can I set instance root volume storage type during its deployment ?
My guess is that the image used has ``*cinder_img_volume_type*`` property set to __DEFAULT__ else there is no way cinder prefers __DEFAULT__ type over any other in this case. Also if you're using victoria release and no volume is using the __DEFAULT__ type then you can delete it as well.
