Today I repeated the procedure described in the link here above and
finally I was successful. Maybe yesterday I was too quick to fall back
to the original state but my enviroment is in production and I was scared...

I had some problems while enrolling the new certificate on the
hypervisors, but removing/rebooting/readding did the trick.

Our engine have an SSO_ALTERNATE_ENGINE_FQDN (before it was the real
engine FQDN) so I found that ImageProxyAddress was still pointing to the
old name. I'm now able (as before) to access the admin portal with both
names but only one (the one with the green lock in the browser) is the
FQDN in the certificate, so I did:

engine-config --set ImageProxyAddress=realFQDN:54323

and now I have sha256 certs and ovirt-imageio-proxy working as expected. :)

Thanks for your hints..
