Created attachment 704825 [details] log_collector Description of problem: 1) When VNIC is unplugged from a VM, log message says plugged=true and when VNIC is plugged, plugged=false (See Additional info for full log line) Hotplug itself works fine, just the log is wrong. 2) GUI event message could be improved now it says that VNIC was updated, but does not say how Interface nic2 (Red Hat VirtIO) was updated for VM F18. (User: admin@internal) if possible change it to Interface nic2 (Red Hat VirtIO) was plugged for VM F18. (User: admin@internal) Interface nic2 (Red Hat VirtIO) was unplugged for VM F18. (User: admin@internal) - see screenshot Version-Release number of selected component (if applicable): SF9 How reproducible: 100% Steps to Reproduce: 1. Create VM with 1 VNIC and OS supporting hotplug 2. Start VM and plug/unplug the VNIC Actual results: plugged = false in log when VNIC is plugged plugged = true in log when VNIC is NOT plugged Expected results: plugged = true in log when VNIC is plugged plugged = false in log when VNIC is NOT plugged Additional info: It would be nice if all boolean values were grouped together in the following log line 2013-03-04 09:17:31,009 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HotUnplugNicVDSCommand] (ajp-/127.0.0.1:8702-8) [1a4b1955] START, HotUnplugNicVDSCommand(HostName = dell-06, HostId = 4ebe3c1b-6fb7-4de6-8045-3459fad14131, vm.vm_name=F18, nic=VmNetworkInterface {id=9ef89efd-6073-4fa0-9ac5-902c301ed7d6, networkName=rhevm, speed=1000, type=3, name=nic2, macAddress=00:1a:4a:22:3f:29, active=true, linked=true, portMirroring=false, vmId=be00921f-365f-42bb-99d0-b33b4a097c1b, vmName=F18, vmTemplateId=null}, vmDevice=VmDevice {vmId=be00921f-365f-42bb-99d0-b33b4a097c1b, deviceId=9ef89efd-6073-4fa0-9ac5-902c301ed7d6, device=bridge, type=interface, bootOrder=0, specParams={}, address={bus=0x00, domain=0x0000, type=pci, slot=0x08, function=0x0}, managed=true, plugged=true, readOnly=false, deviceAlias=net0}), log id: bd82abd 2013-03-04 09:17:31,315 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HotUnplugNicVDSCommand] (ajp-/127.0.0.1:8702-8) [1a4b1955] FINISH, HotUnplugNicVDSCommand, log id: bd82abd

Regarding 1: the printed nic properties are part of log mechanism which prints the entity passed to VDS command. It reflects the current value of the property, prior to the execution. Therefore if the nic should be plugged, its 'plugged' property value would be 'false', since this is its actual value. If it causes any confusion, we can remove the properties from the log for this specific action. Regarding 2: There are 2 separate commands which are equivalent to performed commands: The Add/Update command and the Activate/Deactivate command. The log should present both of them when performing plug/unplug via the Add/Update vnic commands. And basically this is what is shown on the log: 'Deactivate nic' message followed by 'Update nic' message - two messages which reflects the performed actions.
Hello Moti, thanks for the clarification 1) I would not remove it, I consider more information better in this case 2) I think problem is the word "activate/deactivate" since it appears after "plug/unplug" action in the GUI If activate/deactivate could be changed to plug/unplug, it would be perfect.
Please ignore comment 3, I see you already did it.
VERIFIED Network Interface nic1 (Red Hat VirtIO) was unplugged from VM F18. (User: admin@internal) Network Interface nic1 (Red Hat VirtIO) was plugged to VM F18. (User: admin@internal)
