[Bug 1538484] Re: Renaming Flavors
See http://docs.openstack.org/openstack-ops/content/flavors.html for an
explanation. The dashboard simulates editing a flavor by deleting the
old one and creating a new one, which is why the id changed. Your VM is
still associated with the original flavor because the original flavor
was never actually modified. This is by design and not a bug.

The flavor is used by the VM 'astra-test-vm'.

I renamed the flavor 'astra-test-flavor' to 'astra-test-renamed' via
Horizon here. I can see that the flavor ID changed, too. That's wrong.

Still the flavor with old ID can be retrived by 'flavor-show' command,
but it's not in 'flavor-list'. That does not look right.

The VM 'astra-test-vm' still uses the flavor with the old name and old
ID. That's wrong.
