Hi,
I am successfully importing VM from Xen server at oVirt project via virt-v2v. I am setting ssh-agent and running ssh-add before the import process, after the import done I am trying to kill the agent via: ssh-agent -k (and setting the SSH_AGENT_PID environment), but I get the following error: kill: No such process
Can you please explain why there is no agent?
When you run:
eval `ssh-agent` 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

ssh-agent starts up and creates several environment variables (which are added to the environment, because you use the eval `..`). In particular it sets SSH_AGENT_PID to its own PID.
ssh-agent -k is supposed to read SSH_AGENT_PID from the environment and kill the previously started ssh-agent process, basically killing that PID.
It works for me and for lots of other people, so I'm guessing you must either be running ssh-agent wrongly the first time, or getting the SSH_AGENT_PID environment variable mixed up somewhere.
Do I need to delete the agent?
Not necessarily, but if you don't kill the agent then two bad things can happen: (1) You get lots of ssh-agent processes building up (2) The ssh-agent processes may be storing your unencrypted private keys. Except that ...
btw I am also running 'ssh-add -d' after the import process with no problems.
... ssh-add -d will remove the private key from the agent. However the agent should still be running after this, so it would have no effect on whether ssh-agent -k would succeed.
