[ovirt-users] Upgrading oVirt 3.6 with existing HTTPS certificate signed by custom CA to oVirt 4

Thu Oct 27 19:26:21 UTC 2016

Since you replace ca.pem you need to replace the private key of ca.pem

Please copy the private key of  /etc/pki/ovirt-engine/ca.pem to
/etc/pki/ovirt-engine/private/ca.pem and let me know if everything works
