Subject: [Openstack] Error in ssh key pair log in


I am trying to login into VM from host using ssh key pair instead of password. I have created VM using keypair khayamkey and than tried to login into vm using following command

ssh -l tux -i khayamkey.pem 10.3.24.56

where tux is username for VM, but I got following error

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!Someone could be eavesdropping on you right now (man-in-the-middle attack)!It is also possible that a host key has just been changed.The fingerprint for the RSA key sent by the remote host is52:5c:47:33:dd:d0:7a:cd:0e:78:8d:9b:66:d8:74:a3.Please contact your system administrator.Add correct host key in /home/openstack/.ssh/known_hosts to get rid of this message.Offending RSA key in /home/openstack/.ssh/known_hosts:1
  remove with: ssh-keygen -f "/home/openstack/.ssh/known_hosts" -R 10.3.24.56
RSA host key for 10.3.24.56 has changed and you have requested strict checking.Host key verification failed.

P.S: I know if I run ssh-keygen -f "/home/openstack/.ssh/known_hosts" -R 10.3.24.56 problem can be solved but than I have to provide password to log in to VM, but my goal is to use keypairs NOT password.
