1. Please compress logs. 2. Please copy-paste relevant exception (so in the future, it'll be easier to search for dups in Bugzilla). In this case, I believe this is: 2016-10-30 12:48:43,829 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default task-6) [] Operation Failed: WFLYEJB0442: Unexpected Error

(In reply to Yaniv Kaul from comment #5) > Allon, I missed the issue - I think there are some circular calls - > specifically, the interesting part is actually at the bottom of the stack: IIUC, the circular call is a symptom of the problem, not the root cause. The constructor attempts to initialize the storagePoolID, and if it were to succeed this entire issue would have been avoided. The first problem is that it calls getVM() in the constructor. However, this method depends on a DAO call, so using it in a constructor just won't work now that the DAOs are injected (not that it was a particularly great idea to begin with, mind you). Even worse is the fact that getVM() doesn't just fail when it attempts to use a null vmDao, it CATCHES THE EXCEPTION AND HIDES IT (which is an awful idea), thus obscuring the root cause from us. If this theory is correct, patch https://gerrit.ovirt.org/65948 should address this issue. I'll build it locally and see if it resolves the issue on my setup. If it does, I'll merge. If it doesn't, this patch should probably still be merged, but we're back to the drawing board with this BZ.

Patch was merged, and should be available to QA on the next nightly build.
