Hello Socorro.
This patch I proposed was not applied. So the arguments you're using to
create a new storage volume are not correct.
To create a new storage volume allocated to a specific VM, you need
execute two REST requests:
1. POST /storagepools/<pool>/storagevolumes {capacity:..., format:..}
2. POST /vms/<name>/storages {vol:..}
The idea for UI is, in storage tab of the VM edit screen, add the option
to create a new empty storage volume, asking the user the capacity and
format for the new volume. Then, UI will execute the above 2 POSTs
requests to create the volume and attach it to the VM the user is editing.
Best regards,
Paulo Vital.

Hi Paulo/Aline,
I've been working on the UI for this and ran into some errors.
Therefore, before proceeding, I thought I'd run the curl command just to
make sure I'm able to create this new storage volume w/out the UI's
involvement. Here's the error that I got:
I would've thought the API would create whatever was needed in order to
be able to create new storage volume. What am I doing wrong?
Thanks!
