Set a non disk resize (only CPU/RAM changes) to happen without the disk copy

Registered by Jesse Pretorius on 2014-01-09

Currently all resize operations presume a disk resize, making the resize operations take a lot longer than they should for CPU/RAM changes.
Ideally if the resize only involves a CPU/RAM change then the resize should be done on the same host without the disk copy, assuming the appropriate resources are available on the host (or the instance is booting from block/shared storage).

This is more of a feature request. I'd be happy to start a blueprint, but would need to be paired with someone to complete it. Perhaps it'd be better to arrange an IRC discussion about the request, then decide how to handle it? --odyssey4me (29 May 2014)
