Yes - very different. If you don't use the eval then no SSH_* environment variables are set. What probably happened just after that is you added the key to your X session's ssh-agent -- most desktop session managers start an instance of ssh-agent for you. Another way to run ssh-agent which may be more appropriate for scripting is: ssh-agent command args ... which runs the command straight after and kills ssh-agent when the command ends. It would be tempting to run: ssh-agent virt-v2v ... but that won't work because you still have to arrange for the ssh key to be added to virt-v2v's instance of ssh-agent.
