Hello,

I’m trying to boot an instance from a cinder volume, on a specific volume\_type. I’m a little bit lost because :

- In **os\_server** , you can specify **boot\_from\_volume** but there is no **volume\_type** parameter.
- In **os\_server** , if I use **volume** parameter, the root disk is ephemeral, cinder disk is attached aa a second volume.
- If I use **os\_volume** ressource (and boot\_volume in os\_server), I can specify an **image** , but there is no **bootable** parameter, so I can’t boot on it. (So what is the purpose of image ?)

Do I miss something, or my usecase is not impemented in these ansible modules ?

Regards,

Pierre Freund
