Description of problem: Editing network interfaces when using NetworkManager doesn't work Version-Release number of selected component (if applicable): NetworkManager 0.8.998 virt-manager 0.8.7 How reproducible: 100% Steps to Reproduce: 1. start virt-manager and authenticate 2. go Edit-> Connection Details 3. go to the last tab (Network Interfaces) 4. try to Stop the eth0 interface. Actual results: virt-manager hangs Expected results: Allow me to edit the interface. Additional info:
Did some more testing. Stopping NetworkManager allows you to start/stop the interfaces from inside virt-manager. A small comment on bringing my interface up and down. While doing this i did not have a network cable attached to the interface plus am running dhcp on eth0. Now ifup eth0 returns exitcode 1 because it could not get a dhcp adress. While this is correct behaviour inside virt-manager you get an error thrown. This is more a beauty error but shrug... To reproduce: 1. set up eth0 to use dhcp 2. Stop NetworkManager if running (systemctl stop NetworkManager.service) 3. make sure eth0 is unplugged. 4. go Edit-> Connection Details 5. go to the last tab (Network Interfaces) 6. try to Stop/Start the eth0 interface.
virt-manager shouldn't hang here anymore, since we run this command asynchronously. Try virt-manager in updates-testing. That doesn't mean that eth0 shutdown is going to work if NetworkManager is running though, since they tend to collide.
