metadata for instances that boot from volumes
In my environment all instances boot from cinder volumes. So when I launch an instance I do so by creating a volume using an image as the source. Then I launch the instance using the volume as the boot source.
I am trying to modify he instances metadata to add a RNG device using
glance image-update --property hw_rng=true <UUID>
But my concern is that the metadata does not survive through my instance launching process because the instance is launched with a volume as the source rather than a glance image.
I would like to know if my assumptions about why this is not working are correct, and if there is a way I can overcome this.
