This is not a valid, ~cloud/.ssh/id_rsa.pub - doesn't exist. Who should create it?

the cloud user is created by cloudstack.

I tested on two management servers.
the cloud users have different home directories on ubuntu and rocky. This is why I suggested.

  • ubuntu 24.04
# ls -l ~cloud/.ssh/id_rsa.pub 
-rw-r--r-- 1 cloud cloud 594 Mar 14 16:19 /var/lib/cloudstack/management/.ssh/id_rsa.pub
  • rocky8
# ls -l ~cloud/.ssh/id_rsa.pub 
-rw-r--r--. 1 cloud cloud 202 Mar 14 10:14 /var/cloudstack/management/.ssh/id_rsa.pub

I think @weizhouapache 's suggestion is valid. We could add a remark that "the actual user may differ depending on your configuration".

- Add the copied key to /root/.ssh/authorized_keys file on the host

Select "System SSH Key" and proceed with next steps.
