Revision history [back]

snapshot defaults to qcow2

Hi,

I have Juno setup in HA, and able to create snapshots without a problem. Originally I had qcow2 images, so the problem didn't occur to me. I have since then converted the images into raw format, and re-uploaded to glance.

Now after creating an instance from the revised image, and then creating a snapshot by using nova image-create the resulting image is still qcow2

The comment in /etc/nova/nova.conf above the line snapshot_image_format, suggests that the snapshot image would be the same format as the source image. But in this situation doesn't seem to be true.

On another hand the resulting disk in /var/lib/instances/ is a qcow2 image.

Could someone enlighten me on this, to see if this is correct or not
