+Starting 4.11.1, a KVM host is considered secured when it has its keystore and
+certificates setup for both the agent and libvirtd process. A secured host will
+only allow and initiate TLS enabled live VM migration. This requires libvirtd
+to listen on default port 16514, and the port to be allowed in the firewall
+rules. Certificate renewal (using the `provisionCertificate` API) will restart
+both the libvirtd process and agent after deploying new certificates.
