Comment 1 for bug 1301626

In Nova, each keypair belongs to a user not a project. It is a nova behavior. In my understanding, the behavior is reasonable because sharing a keypair means all folks in a project share one private key and it is not a good idea from security perspective. If you need to share a VM, you can add ssh public keys to VM's authorized_key to share a VM.

I mark this bug "Won't fix" as Horizon.
If you need to discuss this behavior further, please discuss it on ML or add Nova to "affected projects".
