<div>Amit,</div>
<div><br>
</div>
<div>For Glance, all the user-specified image metadata must be String data type.</div>
<div><br>
</div>
<div>You can see this in the image schema [0], where "additionalProperties": {"type": "string"}</div>
<div><br>
</div>
<div>(The only image properties that are *not* strings are those assigned non-string types in the schema.)</div>
<div><br>
</div>
<div>So for your example, you need:</div>
<div> metadata = {'hw_numa_nodes': '2'}</div>
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div>Hope that helps!</div>
