How much time is expected to complete Verify Test?

I am trying to run NAS Test suite and during first step of Verify there are bunch of errors.

It is taking around 1 hour to run and fail somewhere. Once I take some action to fix the problem it takes another 1+ hour to find next problem which is very time consuming.

My question is, is it expected time (1 hr+) to execute Verify step? When I fix something, it takes another hour to find next problem.

Moreover I see failures inconsistently. For first run if there are failures to not ping STAFProc on Linux VM, then for second it will pass but fail to retrieve management IP address for another linux VM

Thanks in advance!
