Anyway, you should check the certificates in /etc/pki/vdsm/certs on both the source and destination hosts: - cacert.pem should be the Engine CA certificate. - vdsmcert.pem should be a certificate signed by the CA certificate, with the right host name and not expired. If you are using encrypted migrations then you should additionally check the certificates in /etc/pki/vdsm/libvirt-migrate. cacert.pem should be the CA certificate, server-cert.pem a valid certificate signed by the CA certificate and there should be links client-cert.pem and client-key.pem to server-cert.pem and server-key.pem respectively. > hosts certificates was renewed recently but hosts hasn't been reloaded > how to fix this issue Regards, Milan
