Running oVirt 4.4.5 VM cannot migrate between hosts. vdsm.log contains the following error: libvirt.libvirtError: operation failed: Failed to connect to remote libvirt URI qemu+tls://ovhost01.local/system: authentication failed: Failed to verify peer's certificate Certificates on hosts was renewed some time ago. How this issue can be fixed ? Thank you.
