It can also be done by external system to do the mapping of UUID, but not to change the API.

When I develop Windows app, for example CListBox, for each list item, you can set item-data(four bytes). Sometimes I use the item-data to store the index or pointer of the object the item belongs to.

If the user click the list box, and select one item, the regarding object could be find very fast.

This is also not good idea for we have to change the API and  “that's ripe for a DOS“ (rpodolyaka at mirantis.com<mailto:rpodolyaka at mirantis.com>).

So I admit that I give +1 too early.  Thanks to Joe and rpodolyaka.

Whats the use case for this? We should be thorough when making API changes like this.

Or at least provide a way to specify an external UUID for the instance, and can retrieve the instance through the external UUID which may be linked to external system's object.

主题: [openstack-dev]  [nova] Create an instance with a custom uuid

Hello

I would like to be able to specify the UUID of an instance when I create
it. I found this discussion about this matter:
https://lists.launchpad.net/openstack/msg22387.html
but I could not find any blueprint, anyway I understood this
modification should not comport any particular issue.

Would it be acceptable to pass the uuid as metadata, or should I instead
modify the api if I want to set the UUID from the novaclient?

Best regards
