[ovirt-users] SSL Workflow for oVirt

[Gabriel Stein]

Hi all,

I think that I found a way to solve the problem from:
http://lists.ovirt.org/pipermail/users/2018-January/086441.html and I'm
trying to fix it.

But my servers are in Production(50%) and I found that are some errors with
my SSL Certificates.

## What I need now? Fixes all certificates problems using my Freeipa
generated certificates: vdsmclient* on hosts, ovirt-engine communication
ssl certificates on  hosted-engine.

I made with Freeipa(internal) the certificates for ovirt-engine( only
apache - self hosted) and Hosts(vsdmclient and vdsmkey....) and replaced
using this howto:

https://gist.github.com/qrkourier/9c9ac3e8b190dcb91d3767179d5a39ea

## Now ovirt-engine can't contact a Host(Non Responsive) with the
errors(Yes, I have a Backup from all old certificates):


*VDSM host.domain.tld command GetCapabilitiesVDS failed: General SSLEngine
problem*

On engine.log:

*2018-01-23 13:33:40,160+01 ERROR
[org.ovirt.engine.core.vdsbroker.vdsbroker.GetAllVmStatsVDSCommand]

VdsIdVDSCommandParametersBase:{hostId='d6bc650b-7edd-4019-b316-54313217880f'})'
execution failed: VDSGenericException: VDSNetworkException: General

[org.ovirt.engine.core.vdsbroker.monitoring.PollVmStatsRefresher]
(EE-ManagedThreadFactory-engineScheduled-Thread-23) [] Failed to fetch vms
info for host 'host.domain.tld' - skipping VMs monitoring.*


## I read, that ovirt-engine generates certificates for all hosts and it
uses his own CA.


Questions:

- How can I fix the communication from hosted-engine and vsdm on hosts?
Should I copy my Freeipa ca.crt and replace the ca.der file on
*/etc/pki/ovirt-engine/certs*?

- Should I  change the engine.cer certificate from */etc/pki/ovirt-engine/certs
*with my Certificate made using Freeipa?

- How to do that properly?

- Where can I find a complete workflow from SSL Certificates from oVirt?
What certificates should I change?

## I found some links that to me are confusing(or I'm just dumb), I will
take my end solution and do a howto to all:

- https://www.ovirt.org/develop/release-management/features/infra/pki/ -
how updated is that? I can't overwrite a ca from ovirt-engine?

- https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ *- *
*Note:** Using a commercially issued certificate for HTTPS connections does
not affect the certificate used for authentication between your Engine and
hosts. They will continue to use the self-signed certificate generated by
the Engine... *

... Well, why I keep receiving errors with the self-signed CA from
ovirt-engine and the disk uploads?(*Unable to upload image to disk
a-b-c-d-e 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 certificate can be fetched from
https://<engine_url>/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA*
)

Thanks in Advance!

Best Regards,

Gabriel
PS: I would help with the oVirt Wiki if needed, I would follow the rhce
path and do the rhcs certification too, will be nice to study a lot.
