When a client wants to establish a TLS connection with libvirtd, a CRL file， CA cert and server cert/key are used. Right now, if these files are changed, you must restart libvirtd to make them take effect. The restart behavior of libvirtd will cause clients connecting with libvirtd to fail. In a server cluster, these files, mostly the CRL, may be updated quite frequently dueto the large amount of certificates. If the new file does not take effect in time, there are security risks. So you may need to restart libvirtd frequently to make the CRL etc. take effect in time. However, frequent restarts will affect the reliability of cluster virtual machine management(such as openstack) services. These patches add a virt-admin command to update the tls related files *online*.
