[ovirt-users] Cannot start VM after upgrade - certificate issue

Hello, after running a PoC oVirt setup for more than a year, I ran into the "expiring certificate issue". Done an full upgrade for 4.4, engine-setup, and "Enroll certificates" to all hosts, all hosts are now green, and the certificates are renewed: - /etc/pki/vdsm/certs/vdsmcert.pem - /etc/pki/vdsm/libvirt-spice/server-cert.pem - /etc/pki/libvirt/clientcert.pem - /etc/pki/vdsm/libvirt-migrate/server-cert.pem But: I cannot start any VM any more. Getting: engine.log:2022-08-16 16:34:36,209+02 ERROR [org.ovirt.engine.core.bll.RunVmCommand] (EE-ManagedThreadFactory-engine-Thread-213) [60c5f661-6231-4e03-87a5-f6e6f2c63ad1] Command 'org.ovirt.engine.core.bll.RunVmCommand' failed: EngineException: (Failed with error NotAfter: Mon Aug 15 09:15:42 CEST 2022 and code 5050) Any ideas?
