We aren't using SLES auto-install. But I did google for "SLES
127.0.0.2" and found this at
http://www.novell.com/documentation/novellaudit20/readme/novellaudit20_r
eadme.html:
2.8 SLES 10 hosts File
SLES 10 includes two localhost entries in the /etc/hosts file:
127.0.0.1 and 127.0.0.2 .
The steps for installing Oracle10g on SLES10 at
http://wiki.novell.com/index.php/Oracle10g_R2_Database_on_SLES10_for_i38
6_Step-by-Step_1 also reference commenting out the 127.0.0.2 line.
Please add this step to the OFED 1.1 MVAPICH release notes.
