The relevant piece from vdsm.log is the following which indicates VDSM has a specific error code 29 which doesn't appear on engine.
Thread-101586::ERROR::2013-08-01 10:56:26,890::API::1261::vds::(setupNetworks) Determining IP information for VLAN170... failed.
Traceback (most recent call last):
File "/usr/share/vdsm/API.py", line 1259, in setupNetworks

raise convert_to_error(kind, result)
ConfigNetworkError: (29, 'Determining IP information for VLAN170... failed.')
However, code 29 ERR_FAILED_IFUP serves multiple errors raised by vdsm and not a specific one. The engine has a static mapping of VDSM errors, therefore I don't think that a generic message of "Failed to bring interface up" without an interface name in SetupNetwork action which serves multiple actions will reveal enough information and will reduce the need of the user to look at the logs.
I'll add the generic IFUP failure message so it can be used by other commands to which it might be relevant (e.g. addNetwork).
verified on is 15 gui provides Error while executing action Setup Networks: Failed to bring interface up and vdsm log error = Determining IP information for no_dhcp... failed. *** Bug 1001090 has been marked as a duplicate of this bug. *** Closing - RHEV 3.3 Released Closing - RHEV 3.3 Released |
Created attachment 781485 [details] log_collector Description of problem: When obtaining IP from DHCP fails, reason is clearly mentioned in engine.log Failed to SetupNetworksVDS, error = Determining IP information for VLAN170... failed. but GUI show just "Error while executing action Setup Networks: Unexpected exception" it would be helpful for the users to get clear explanation what went wrong. Version-Release number of selected component (if applicable): Red Hat Enterprise Virtualization Manager Version: 3.3.0-0.11.master.el6ev How reproducible: 100% Steps to Reproduce: 1. create logical network and attach it to host 2. specify that network should obtain IP from DHCP (while there is no DHCP on the network) Actual results: "Error while executing action Setup Networks: Unexpected exception" Expected results: "Error while executing action Setup Networks: Determining IP information for VLAN170... failed." Additional info: 2013-08-01 09:57:59,459 ERROR [org.ovirt.engine.core.bll.network.host.SetupNetworksCommand] (ajp-/127.0.0.1:8702-8) Command org.ovirt.engine.core.bll.network.host.SetupNetworksCommand throw Vdc Bll exception.
