Version-Release number of selected component (if applicable): vdsm-4.17.31-0.el7ev.noarch rhevm-3.6.8.1-0.1.el6.noarch How reproducible: 100% Steps to Reproduce: 1. Create a bonded network and attach one vlan tagged network and untagged network to this bond. 2. Modify the untagged network and add a vlan tag. 3. "Bridge=" parameter is not deleted from the bond ifcfg configuration file which will create network loop and vdsmd will not start after this. Actual results: "Bridge=" parameter is not deleted from the bond ifcfg configuration file when changing a untagged network to tagged Expected results: "Bridge=" parameter should be deleted from the bond ifcfg configuration file when changing a untagged network to tagged Additional info:
