Hey all, Recently, Nova added support for multiple zones in the OpenStack API. Using the nova-manage tool, you can get a list of instances in a single zone or in multiple zones using the --recurse option. When just querying a local zone's API server, the listed instance identifiers will be integer IDs. When using the --recurse option, the listed instance identifiers are UUIDs since they are globally unique.
Multiple zones is currently only supported in the OpenStack API, and the question has been raised whether effort should be expended to get parity in the EC2 API for this. The problem with the EC2 API is that we do not have control over the instance identifiers -- they are an 8 character text string. We would still need to map the EC2 instance identifier to some globally unique identifier (like a UUID), but the solutions for how to do this aren't pretty (see http://etherpad.openstack.org/EC2UUID). Personally, I don't think it is worth expending the effort to get this feature parity between the OpenStack API and the EC2 API, especially considering we have little (or no) control over the EC2 API. Thoughts? -jay _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
