The odd thing about this is that Horizon simply uses the same exact REST
APIs that you would be using when you use the Nova python CLI.  Horizon
doesn't have a different interface than the CLI would.

When you tried both the nova CLI and Horizon interface, were you
migrating between the exact same hosts?  Perhaps your SSH keys are set
up properly between the hosts that were involved in the CLI migration,
but are not set up properly between the hosts uses in the Horizon
initiated migration?
