 Review comment:
   Alright @wido, perhaps we can remove this for Ubuntu (debian pkg). On both 
CentOS 6 and 7, iptables service is indeed available that is used to save 
existing rules, firewalld is not used here. It is likely that things may break 
for el6/7 users. I'm okay to document the change in release notes docs as well. 
Let's ask others for their thoughts - @DaanHoogland @rafaelweingartner @resmo 
@ustcweizhou @nvazquez @mlsorensen ?

> 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.
