The oVirt's CA certificate can be fetched from http://<engine_url>/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA

(more details in 'SSL installation' section at: https://github.com/oVirt/ovirt-imageio/blob/master/proxy/README).

For importing the certificate to firefox, try the following instruction demo :

Thanks! But I don't know how to import CA to browser. I have tried to import the CA to my firefox browser, but I failed. Is there any documentations about that?

Most probably it's ovirt engine CA certificate. You need to import it to your browser.

Hi all,
        I wanted to upload a qcow2 image using web UI. But I got an error:
 "Unable to upload image to disk a38f29f4-594a-438b-a8e0-6a85ac56055d due to a network error. Make sure ovirt-imageio-proxy service is installed and configured, and ovirt-engine's certificate is registered as a valid CA in the browser."
        The ovirt-imageio-proxy service had been installed when I excuted "engine-setup". What shoud I do about ovirt-imageio-proxy or CA? Hope someone can help, thanks!
