can't add host in cloudstack cluster

[yann1ck-oder-so]

Hello everyone,

I’m currently stuck with the following issue:
I have a management server and a KVM host, both running on Ubuntu.
I can access the CloudStack GUI and have completed the initial setup.

Now I’m trying to add the KVM host — I’ve attempted both the SSH key and password methods.
Unfortunately, both fail with the following error:

Error 530
Could not add host at [http://cs-wn2-iwa] with zone [Zone {"id": "1", "name": "Berne-IWA"}] ...
due to: [Authentication error with ssh private key].

According to the official documentation:

Copy the SSH public key from /var/cloudstack/management/.ssh/id_rsa.pub on the management server
Add the copied key to /root/.ssh/authorized_keys on the host
While adding the host from CloudStack UI, select “System SSH Key”

However, the directory /var/cloudstack/management/.ssh/ does not exist on my management server.
So I don’t have any id_rsa.pub file and I’m wondering whether the documentation is outdated or if I missed a step during setup.

Has the location or procedure changed in recent CloudStack versions?
Or how can I correctly generate and configure the system SSH key for host authentication?

Thanks in advance!

If you use RHEL or variants, the directory /var/cloudstack/management/ is correct
If you use Ubuntu, the directory should be /var/lib/cloudstack/management

You can get it by

# echo ~cloud
/var/lib/cloudstack/management
