Comment 5 for bug 1688054

@Matt, I have found few more references here, I think we should recheck this functionality
https://docs.openstack.org/cli-reference/glance-property-keys.html
https://docs.openstack.org/admin-guide/cli-manage-flavors.html

can you go through following links and update us little more,
https://wiki.openstack.org/wiki/NetworkBandwidthEntitlement
https://serverfault.com/questions/656582/what-does-rxtx-factor-mean-what-is-it-and-how-does-it-affect-my-server

I am not sure, this factor really works with KVM or not.
