If (unlike me) you believe that this is a Vdsm bug, please report vdsm version and supply vdsm.log (look for vmCreate and hence). Would you copy the output of `vdsClient -s 0 getAllVmStsat` from the host? I'd like to see what confuses Engine. Whatever Vdsm reports, Engine should not get itself into java.lang.NullPointerException. Please see Dan's comments. The vdsm version, logs and Vm stats are important for debugging the engine crash as well. Created attachment 829747 [details]
vdsClient -s 0 getAllVmStats on the hypervisor Buran
Included in 3.3.2 beta rc build done, moving to ON_QA, packages will be available on updates-testing repository. oVirt 3.3.2 has been released resolving the problem described in this bug report. |
Description of problem: VDS error when launching a new vm or starting a excisting vm after update to 3.3.1. The error: Failed to refresh VDS , vds = 7ab1a0d7-8c72-44d1-9cb5-320c456be77d : progress, error = java.lang.NullPointerException, continuing.: java.lang.NullPointerException at

Reproduce: 1.Launch a new vm (or existing one) after the update from 3.3 to 3.3.1, leave the option "Memory Balloon Device Enabled" under "Resource allocation" off 2.Start the vm and check the engine.log Actual results: Your vm won't boot or sometimes after a very long time it does Expected results: Vm should boot Additional info: Before I restarted the ovirt engine I got these errors:
