Thanks for your answer.
I know port 902 is open for the host I am choosing for P2V.
But when I look in the converter-agent.log as you said, it fails to connect to a host, but it is a different host than I choose in the wizard!
It seem if I choose host 1 (which the port 902 is open) it seems to choose a random host instead of using the one I choose.
It has to be a bug!
