KVM deploy engine

User_ILNWN

I am installing Oracle Virtualization Manager self-hosted engine on Oracle Enterprise Linux 7.9. The installation starts fine but after a while it got stuck at a point and fails. Until now I am not able to identify the root cause of this error or troubleshoot it.

I tried by CLI and Cockpit but the error is the same

[ ERROR ] fatal: [localhost -> CL4A0V-DCC-MG01.cloud.sonda.com]: FAILED! => {"attempts": 12, "changed": false, "msg": "Failed to validate the SSL certificate for localhost:443. Make sure your managed systems have a valid CA certificate installed. You can use validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs, /etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, /usr/share/ca-certificates/cacert.org, /etc/ansible. The exception msg was: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:618).", "status": -1, "url": "http://localhost/ovirt-engine/services/health"}

Could you help me?

Hi.

It's look like at this moment hostname is localhost. It's can be problem.

Assign some hostname with domain. Check that new hostname can be resolved to IP.

Regards,

I don´t have option for change local hosts.

DNS is resolving name to IP withoit problem.

Hi

Thank you for your answer.

I fixed my problem whth the next workaroud.

=======================================================================

1) During the hosted-engine setup, wait for the local VM to be deployed

2) After the local VM is deployed and ovirt-engine packages are installated 

(visible in installation script output) you will have a few minutes to do the following:

Check the HostedEngineLocalVM IP Address in the Hypervisor /etc/hosts

Open up a ssh session to the HostedEngineLocalVM IP and execute the following commands:

# mv /etc/httpd/conf.d/ovirt-enable-strict-transport-security.conf /var/tmp

ll# systemctl restart httpd

3) The installation script is at this stage trying to access to health page with http, 

and it will succeed after step (2) is performed
