Amit,
For Glance, all the user-specified image metadata must be String data type.
You can see this in the image schema [0], where "additionalProperties":
{"type": "string"}
(The only image properties that are *not* strings are those assigned non-string
types in the schema.)
So for your example, you need:
metadata = {'hw_numa_nodes': '2'}
It's a little counterintuitive, but the idea is that Glance has know way of
knowing what kind of metadata you'll want to put on an image, so Glance stores
everything as a string. Since it's your metadata, you'll know what data type
to convert the string to before you use it in a script.
Hope that helps!

Hi,
I am using python-openstackclient and os_client_config
My requirement is, i want to update, my image metadata ....
i made two objects, by which i think i may achieve it:
nova = os_client_config.make_client('compute')
glance = os_client_config.make_client('images')
example: metadata = {'hw_numa_nodes': 2,}
i tried it many things, but not get succeed, like:
n_im = nova.images.get(<image_id>)
nova.images.set_meta(n_im, metadata), or
n_im.manager.set_meta(n_im, metadata)
........ and many other also ..
please suggest what would be the proper way to do it,
Thanks
