Following the above, I was seeing that OVN provider connectivity test
was
failing due to some certificate issue and had to do the following to fix
it:
names="ovirt-provider-ovn"
subject="$(\
openssl x509 \
-in /etc/pki/ovirt-engine/certs/apache.cer \
-noout \
-subject | \
sed \
's;subject= \(.*\);\1;'
)"
. /usr/share/ovirt-engine/bin/engine-prolog.sh
for name in $names; do
/usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh \
--name="${name}" \
--password=mypass \
--subject="${subject}" \
--keep-key \
--san=DNS:"${ENGINE_FQDN}"
done
Having fixed the above, when trying to connect two VMs on some OVN logical
switches it seems they are not able to reach each other.
I had previously added such logical switched at engine by running:
ovn-nbctl ls-add ovn-net0
ovn-nbctl ls-add ovn-net1
etc
Not related: Please use ovirt-provider-ovn to create and manage ovn
entities.
Checking the logs at the host /var/log/openvswitch/ovsdb-server.log I
see:
reconnect|WARN|unix#45: connection dropped (Connection reset by peer)
/var/log/openvswitch/ovn-controller.log might contain the reason.
Also systemctl status ovirt-provider-ovn.service at engine shows:
/usr/lib/python2.7/site-packages/urllib3/connection.py:344:
SubjectAltNameWarning:...
Looks not good, do tou know which connection this warning referes to?
I have restarted at engine both engine and ovn services:
systemctl restart ovirt-engine
systemctl status ovirt-provider-ovn.service
I have also restarted the relevant service at each host:
systemctl restart ovn-controller.service
When running at host the following it stucks and does not give any output:
ovn-sbctl show
This is expected, the ovn southbound and northbound db exists only on the
ovn-central, which is places on the same machine as oVirt Engine.
Only the ovn-controller, which controls openvswitch, and openvswitch, which
is implementing the data plane, is placed on the ovn-chassis / oVirt host.
I see that the certificate is imported at key-store as it has the
same
fingerprint with the previous root CA:
keytool -list -alias ovirt-provider-ovn -keystore
/var/lib/ovirt-engine/external_truststore
This is only relevant for the connection from oVirt Engine to
ovirt-provider-ovn.
At this same cluster, I had previously changed the domain name of
each
host and engine using the rename tool.
And now replaced the certificates as per previous described so as to fix
the imageio cert issue and ovn issue.
It seems that OVN is not happy with the status of certificates.
When testing connection at engine GUI i get a prompt to trust the cert,
and when pressing ok i get a green confirmation of successful connection.
This is only relevant for the connection from oVirt Engine to
ovirt-provider-ovn. The prompt to trust the certificate might be redundant.
If you get the green confirmation, oVirt Engine is happy and the
certificate of the REST API of ovirt-provider-ovn is fine.
Is there anything else that can be done to fix OVN functionality?
Please try to understand what is wrong in the connection between
ovn-controller and ovn south bound db.
/var/log/openvswitch/ovn-controller.log should be helpful and might contain
the reason.
Thanx
Alex
