> With use of CA framework to secure hosts, the current mechanisms don't secure libvirtd
to use those certificates (used by agent to connect to mgmt server). This causes insecure
vm migration over tcp instead of tls. The aim is to use the same framework and certificates
to secure live VM migration. This could be coupled with securing of a host and renewal/provisioning
of certificates to host.
