virt-manager debug log
I can reproduce this issue with package: virt-manager-1.4.3-3.el7.noarch Then try to verify this bug with new build: virt-manager-1.5.0-3.el7.noarch virt-install-1.5.0-3.el7.noarch libvirt-4.5.0-12.el7.x86_64 qemu-kvm-rhev-2.12.0-26.el7.x86_64 libvirt-python-4.5.0-1.el7.x86_64 1. Check the ip-config window can be closed even for incorrect configuration when creating new host network interface. 1.1 Open virt-manager. 1.2 Open a new 'Configure network interface' dialog. 1.3 Keep interface type as Bridge, click 'Forward'. 1.4 Click 'Configure', then set IPv4 Mode to 'Static'. 1.5 Click 'OK' to make it work. Result: An Error validating IP configuration dialog will pop up:'Error validating IP configuration:Please enter an IP address'. 1.6 Close the error dialog and click the close button 'X' in the upper right corner of the configure network interface dialog. Result: The dialog can not close and the Error as the result of step1.5 will pop up again until changing IPv4 Mode from static to dhcp or none configuration. 1.7 New 'configure network interface' dialog can open successfully. Results:Open host network interface successfully. The result of Step1.6 is confused.I can't close the incorrect configuration directly by click 'X'. It's not ideal but it would require to refactor the code and since this was completely dropped from upstream and I would consider it as a corner case I don't think we should waste anymore time to improve it. Thanks for you replication,so i move this bug from ON_QA to VERIFIED based on above testing.
