ImageUnacceptable: Unsupported image format: qcow2 [closed]

edit

The Windows SMB driver supports only vhd/x images for storing the volumes. I think you are creating a volume using a Glance image, right? In that case, previously, it was converting the qcow2 image to a vhd/x image. Since this is a time consuming task, especially if done often and having large images, we now expect the provided image to be a vhd/x image.

You could convert the image to vhd or vhdx before submitting it to Cinder.
