logs

Description of problem:

I am not sure how to reproduce this but I am seeing in the logs that Query 'GetVmOvfByVmIdQuery' failed: null with  Exception: java.lang.NullPointerException

the actual trace appears in the log only once but the query seems to be failing since that time. 

Version-Release number of selected component (if applicable):

ovirt-engine-4.1.1.2-0.1.el7.noarch

How reproducible:

unknown

Steps to Reproduce:
unknown

Actual results:

I can see in the logs that we keep getting a null exception on vm ovf

Expected results:

we should not fail on the query with exception (at least we need to know what it is and how to fix it if it happens).
