I didn't run eval `ssh-agent` but ssh-agnet and then ssh-add (I
needed the SSH_AUTH_SOCK that return from ssh-agent since I am
running two different processes).
I guess I can read the environment SSH_AUTH_SOCK after run eval
`ssh-agent`...
do you think there is a different between running with to without eval?
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.
