Created attachment 948380 [details] virt-manager-debug.log Description of problem: Start mode can only show as 'none' in Network Interfaces though changed to 'noboot' or 'hotplug' Version-Release number of selected component (if applicable): libvirt-1.2.8-5.el7.x86_64 virt-manager-1.1.0-4.el7.noarch pygobject3-3.8.2-6.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. Launch virt-manager: #virt-manager. 2. Click Edit->Host Details. 3. Click Network Interfaces tab on Host Details dialogue. 4. Click + button. 5. Select interface type as 'VLAN', click Forward button. 6. Select start mode as 'hotplug', enable activate now, Fill VLAN tag as 1, choose eth0 as parent interface. Click Finish button. 7. After eth0.1 showing, check its start mode. 8. Repeated step 6 and step7 again with choosing start mode as 'onboot'. Actual results: Though changed, Start mode just showing 'none'. Expected results: Start mode should show correctly. Additional info: Cannot reproduce this issue with virt-manager version: virt-manager-0.10.0-20.el7.noarch
I found an easier way to address the issue. Patch proposed upstream: https://www.redhat.com/archives/virt-tools-list/2015-May/msg00050.html
I can reproduce this bug with package: virt-manager-1.1.0-4.el7.noarch Steps are the same as description. Then verify with the latest: virt-manager-1.2.0-4.el7.noarch Scenario 1: Uncheck "active now" when create VLAN network Steps: 1. Launch virt-manager: #virt-manager. 2. Click Edit->Host Details. 3. Click Network Interfaces tab on Host Details dialogue. 4. Click + button. 5. Select interface type as 'VLAN', click Forward button. 6. Select start mode as 'hotplug', disable activate now, Fill VLAN tag as 1, configure IP settings as IPV4: DHCP, choose enp0s25 as parent interface. Click Finish button. 7. After enp0s25 appear, start the interface. Check the start mode of vlan network. 8. Repeat step 6 and step7 again with choosing start mode as 'onboot'. Result: 1. After Step 7, start mode was shown correctly. 2. Start the interface, after 1-2 minute, an error message occur. The status of the interface is inactive. Re-enter this tab, the status of this interface become active. Error creating interface: 'Could not create interface: internal error: failed to create (start) interface enp0s25.1: failed to execute external program - Running 'ifup enp0s25.1' failed with exit code 1: Determining IP information for enp0s25.1... failed.

There is no newly created VLAN interface shown in virt-manager.

Check and find a new VLAN network interface was created after Step 6. # ifconfig -a| grep enp0s25 enp0s25: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 enp0s25.1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 As result 1 in scenario 1 shows, the bug itself was fixed. However, when creating VLAN network, problems as Result 2,3 in scenario 1, Result 1,2 in scenario 2 will occur. If possible, could you please give me some more information about this? Thanks for your kindly help!
please file it separately, as it looks as a new issue. What happens if you manually do "ifup enp0s25.1" on the system? What do you get?
I did as you suggested. Step 1, I created an inactive VLAN network and execute: #ifup enp0s25.1 Determining IP information for enp0s25.1...failed. Step 2, I found that after this command, the state of the VLAN network is active, but without ip address for ipv4. #ifconfig enp0s25.1 enp0s25.1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::3e97:eff:fe22:ab2c prefixlen 64 scopeid 0x20<link> ether 3c:97:0e:22:ab:2c txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 14 bytes 2700 (2.6 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Step 3, additionally, when I check the VLAN network status back on virt-manager, the status remains "inactive". However, when I switch to another tab, and then switch back, the network status was refreshed. The status was changed to "active".
please file a different bug for this issue, as it requires more investigation. I've not encountered it while working on this bug, and the proposed fix for 1154480 has no effect on it.
File a new bug according to the issue I mentioned on Comment 8 - bug 1227641 As was mentioned in comment 8, the bug itself was fixed in the latest version of virt-manager. So move the bug from ON_QA to VERIFIED.
