Moving from 4.0 alpha to 4.0 beta since 4.0 alpha has been already released and bug is not ON_QA. Fabrice, I am taking a look at this. and I have some questions. Looking at the stack trace the problem appears to happen when we are trying to read some information from a UI plugin. Are you running oVirt with any UI plugins enabled? If so, which one? You also said you couldn't reproduce but do you remember at all in general what you were doing when this happened? Thanks, Alexander I didn't activate any plugin. That was a few weeks ago, so no, I don't remember what I was doing, sorry. oVirt 4.0 beta has been released, moving to RC milestone. oVirt 4.0 beta has been released, moving to RC milestone. Fabrice, please re-open if reproduces, and also attach all engine and UI logs. Thanks! |
