Daniel, Ricardo
I get your point. Network Manager does not support full features and not
present in older versions before Fedora 20. It will be keep on updating to
support more and more use cases.
Just adding here few point from fedora link.
Detailed description
NetworkManager's existing support for bond interfaces covers a limited
number of use-cases and can conflict with existing bonding configurations
created by tools like libvirt. The purpose of this Fedora feature is to
implement more flexible bonding infrastructure in NetworkManager to support
an expanded number of use-cases and to be more cooperative with other users
of bonding.
Support will be added to NetworkManager to detect the existing
configuration of a bond interface and its slaves and to seamless "take
over" that connection without disrupting it. Even if the existing
configuration is not backed by ifcfg files on-disk, NetworkManager will
leave that configuration on the interface unless told to change it by the
user via GUI or CLI tools. Additional bond interface configuration will be
added to expand the use-cases and hardware that NetworkManager can
configure (eg primary, use_carrier, xmit_hash_policy, etc).
Given that libvirt is the way we proceed for network management in guest.
My question here adding to Suresh is do we need to really warn the user
about other tools like Network Manager? Tomorrow there can be other tools
like cockpit , x , y which do the same task may not be completely. Then in
that case we keep updating our warning?
I feel we should restrict ourselves to kimchi/ginger and make sure the
network management functionality we are implementing are in sync and do not
disturb other tools.
We should keep reading the configurations as long as they are standard
irrespective of which tool is used for configuring. If we have write
permissions we can very well modify those interfaces. If configurations are
not valid we ignore them.

Are we advising end user to block Network Manager permanently?
No. We are advising the user to exercise caution with NetworkManager in
these scenarios.
It is a known fact that NetworkManager started support native bridge and
bonding only in F20*. This Kimchi feature must be supported on older
distros such as RHEL 7.1 that has older NetworkManager versions that
doesn't have this native support.
This is why we have this warning. The user can proceed with the
operation with NetworkManager on, but he's on his own.
