 Review comment:
   Is there an alternative that will work. I would not like to see a large devide between
the amount of work to be done on rhel-like systems versus debian-likes.

> 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.
