Failure on start VM in ovirt-system-tests from patches merged to master on the 25/10/2016

[Nadav Goldin]

Hi,
We have new failure on OST from patches merged to master yesterday,
the failure started after the merge of [1], but as there were quite a
few patches merged quickly I can't make sure it is the one causing
it(OST aren't ran per-patch).
The test that fails is [2] when attempting to start the VM.

The error from the API side:

RequestError:
status: 500
reason: Internal Server Error
detail: javax.ejb.EJBException: java.lang.NullPointerException
    at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInNoTx(CMTTxInterceptor.java:213)

    at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340)
....

In the engine logs there are a few 'java.lang.NullPointerException' errors:

The full engine logs can be found here[3] and the entire test suite
logs here[4].

Can anyone have a look?

Thanks,
