# Nova Bandwidth Limit Issue

Hello All,

I have installed OpenStack with Mirantis Fuel 8.0.

Everything works like charm, except network bandwidth limitation does not work.

I have created flavor with following extra_specs:

quota:vif_inbound_peak = 102400
quota:vif_outbound_peak = 102400


But limitation does not work, there is not a bandwidth tag in libvirt.xml.

Becuase having some problem with vif I have applied following configuration in compute nodes:

vif_plugging_is_fatal=False
vif_plugging_timeout=10


What might be the problem?
