Description Mor 2016-11-13 09:40:37 UTC 
Description of problem:
In a running VM which has vNIC attached to external network, changing the vNIC link state from "Up" to "Down" pops blocking message in the UI.

Version-Release number of selected component (if applicable):
oVirt Engine Version: 4.1.0-0.0.master.20161112231308.git672bd31.el7.centos

How reproducible:
100%

Steps to Reproduce:
1. Create a VM with additional vNIC.
2. Create external network on external network provider.
3. Attach the additional vNIC to the external network.
4. Turn on the VM.
5. Try to unlink the vNIC while VM is running.

Actual results:
"Cannot edit Interface. External network cannot be changed while the virtual machine is running. This is tested with OpenStack Neutron and OVN provider external networks."

Expected results:
Link state should be changed.

Additional info:
Tested both in Neutron and OVN external provider networks.

Comment 1 Red Hat Bugzilla Rules Engine 2016-11-13 09:40:44 UTC 
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.

Comment 3 Dan Kenigsberg 2016-11-13 12:36:30 UTC 
I'm sorry for misunderstanding your initial bug request.

I do not see a current need to support modification of link state in external network providers.

Thanks for opening this bug.
