Cool, so glance internally does some lookup of ‘X-Image-Meta-Store’ and
this will over-ride the default_store?

You can pass the X-Image-Meta-Store: header to one of "swift", "s3", or
"rds". Unfortunately, this is not supported in the glance CLI tool right
now. You could add a quick hack that adds the X-Image-Meta-Store header
to the features variable. Something like this git diff shows...

and try that :)
If it works out, feel free to contribute the patch to Glance ;)

No, but it hasn't been something that users have clamoured for up until
now -- mostly because people standing up Glance are typically standing
it up with some default store and only storing images using that store.
But the "plumbing" is there to support this. as mentioned above.
