Comment 2 for bug 1906849

Greetings,

I just stumbled upon this feature request, as we upgraded our openstack setup to a version which supports metadata over ipv6. While testing it we found that cloud-init does not support this without manually setting the metadata_url over user-data.

Maybe I am too naive, but this does not look to be the hardest implementation if it would be done like in ec2 with a metadata url list which is just tested one by one [1].

Could this be done the same way in openstack where we change [2] to be a list of possible metadata addresses?

Any opinions on this?
