Public bug reported:

The mirror images adopted include:
1. Use xshell, putty, JuiceSSH cannot connect [http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1805.qcow2]
2. Cannot connect with xshell, putty and JuiceSSH [centos7.4 made by myself, no problem with Ocata version built before]
3. With xshell, putty and JuiceSSH, you can connect [http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img]
After the failure, attempts were made to recreate the SSH keys in the system, but to no avail.

The order is as follows:
[root@host-192-168-1-10 ~]# rm -f /etc/ssh/ssh_host_*
[root@host-192-168-1-10 ~]# systemctl restart sshd.service
