On Solaris 10, When trying to log into Oracle VM cli and Oracle VM manager host port 22 with ssh, it is found that ssh client use same entry in ~/.ssh/known_hosts to access both 10000 and 22 ports, while these 2 ports in known_hosts file have different RSA/DSA signatures/entries, which causes below problem.
