Hi,
Since a few weeks, we are not able to connect to the vmconsole proxy:
$ ssh -t -p 2222 ovirt-vmconsole@ovirt
ovirt-vmconsole@ovirt: Permission denied (publickey).
Last successful login record: Mar 29 11:31:32
First login failure record: Mar 31 17:28:51
We tracked the issue to the following log in /var/log/ovirt-engine/engine.log:
ERROR [org.ovirt.engine.core.services.VMConsoleProxyServlet] (default task-11) [] Error
validating ticket: : sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target
Indeed, certificate /etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer and others did
expire:
--
# grep 'Not After' /etc/pki/ovirt-engine/certs/vmconsole-proxy-*
/etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer: Not After : Mar 31
13:18:44 2021 GMT
/etc/pki/ovirt-engine/certs/vmconsole-proxy-host.cer: Not After : Mar 31
13:18:44 2021 GMT
/etc/pki/ovirt-engine/certs/vmconsole-proxy-user.cer: Not After : Mar 31
13:18:44 2021 GMT
--
But we did not manage to found how to renew them. Any advice ?

Hi,
I believe I have the same problem as this.
Same error message in engine log and expired certificates in
/etc/pki/ovirt-engine/certs/vmconsole-proxy-*
Any ideas?

This is a hackish way to generate a new certificate outside of
ovirt-engine.
1. Backup oVirt and especially /etc on engine
2. Generate a new request for the vmconsole-proxy-helper
openssl req -new -out vmconsole.req -subj /CN=MY_OVIRT_FQDN -key
/etc/pki/ovirt-engine/keys/vmconsole-proxy-helper.key.nopass
3. Use the oVirt CA to sign this request to produce a new cert:
cat > extfile.conf <<EOT# lets try to mimic the extensions that oVirt CA
creates
subjectKeyIdentifier=hash
authorityKeyIdentifier=keyid:always,issuer
basicConstraints = CA:false
keyUsage = digitalSignature
extendedKeyUsage = DER:300E060C2B0601040192080D01020101
EOT
Sign the request
openssl x509 -req -CA /etc/pki/ovirt-engine/certs/ca.der -inform DER
-CAkey /etc/pki/ovirt-engine/private/ca.pem -set_serial MY_SERIAL_NO \
-extfile extfile.conf -in vmconsole.req
Then you can use this cert to override
/etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer
Needless to say, this is extremely hackish - and I would like to know the
proper way to work this.
BTW my vmconsole SSH keys/certs also were a) expired b) wrong type ssh-rsa
so I needed to jump
through similar hoops to get proxy -> host working again.
