[Openstack-operators] [openstack-dev] [nova] reset key pair during rebuilding

I agree this feature of injecting a new keypair is something of great
use. We are always dealing with users that cant access their VMs

But AFAIU here we are talking about injecting a new key at REBUILD. So
it does not fit the scenario of a staff member that leaves !

We hardly never use the rebuild feature in our workflow. Our users
just use create and delete.

I think it would be more useful a feature where you can reinject a new
keypair in the VM at any time. Ahhh it makes the users happy but of
course it is a security nightmare :D
