Description Meni Yakove 2012-08-05 07:21:52 EDT
Description of problem:
When attaching network with custom MTU to interface and then removing the network from the interface the custom MTU on the interface is still the custom MTU and not the default 1500. 

Version-Release number of selected component (if applicable):
rhevm-3.1.0-10.el6ev.noarch

How reproducible:
100$

Steps to Reproduce:
1.Create network with MTU 5000 and attach it to cluster.
2.Open SetupNetworks and attach MTU network to interface > apply > check MTU on host, should be 5000
3.Open SetupNetwork and detach MTU network from the interface > apply > check MTU on the host, still 5000 
  
Actual results:
The MTU on the interface is 5000 after detaching the network from the interface.

Expected results:
The MTU on the host should be the default 1500 when detaching network from interface

I don't see how/why we would fix this.
what if the inerface had an MTU of 8000 before?
we don't keep this value to restore it.

Then configuring to 1500 will be just as good.
Certainly better than keeping it with a higher value.
