As the default interval for the OpenNebula monitor probe is 600 seconds (10 minutes), each time a probe reactivates libvirtd, it sends those messages to syslog.
 
+- Due to `Missing automation for enabling vTPM support <https://github.com/OpenNebula/one/issues/7422>`_ issue one needs to perform several additional steps on hypervisor nodes to make the vTPM work with OpenNebula. Please, find these steps below.

+Add the following lines into the ``/etc/libvirt/qemu.conf`` file:
+
+.. prompt:: bash $ auto

+
+and restart libvirtd.service:
+
+.. prompt:: bash $ auto
+   
+   systemctl restart libvirtd.service
+
+Change the ownership of ``/run/libvirt/qemu/swtpm/`` and ``/var/lib/swtpm-localca`` dirs:
+
+.. prompt:: bash $ auto
