correct live reisze is not supproted and not planned to be supported in a future release.

you can extend the disk live if its a boot form voluem instance but nova resize api is and will
continue to be an offline operatoion. live resize wiht qemu/kvm has a lot of edge cases like
startign the domain with the maxium ram set to the largeset value you might resize too and setting current
to what is in the flavor. the same would be required for cpu. its really not something that is compatible with how
we do flavor as there are too many ways that it could fail without signifciatly modifying how flavors work.
