To clarify a bit more, if I build Xen on the same machine without PAE 
enabled, I do not see the problem. Further, the xm-test failures are due 
to this problem:

               Platform | PASS | FAIL | XPASS | XFAIL |
---------------------+------+------+-------+-------+

        x335sles9_pae4gb |   65 |   26 |     0 |     1 |               
<==============PAE enabled results

...
    x335sles9_pae4gb |   87 |    2 |     1 |     0 |      <========== 
Same machine, non-PAE.
