在需要迁移VM的节点主机上操作：
ssh -o 'HostKeyAlias=<Target node Name>' root@<Target node IP>按实际情况更改为迁移目标节点的信息：
ssh -o 'HostKeyAlias=H2-vps02' [email protected]如果出现以下提示：
root@H1-vps19:~# ssh -o 'HostKeyAlias=H2-vps02' [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 is SHA256:HGFz17oiODFDFDS437bBKLFDKLEGfepL5IFFbDdWkec. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message.

那按上面执行：ssh-keygen -f "/etc/ssh/ssh_known_hosts" -R "H2-vps02" 然后再次执行： ssh -o 'HostKeyAlias=H2-vps02' [email protected]
