[GONG Jie]

This is openstack baremetal related problem.

The testing environment is RHEL6.4 on x86-64. The following rpm packages were installed and used.

While I was trying to start up the openstack-nova-compute service. The service did not start up at all.

[root@dx360m4n05 ~]# service openstack-nova-compute start
Starting openstack-nova-compute:                           [  OK  ]

19163
[root@dx360m4n05 ~]# ps ax | grep -v grep | grep 19163

The error message looked like this.

[root@dx360m4n05 ~]# cat /var/log/nova/compute.log2014-03-17 12:51:25.852 17872 CRITICAL nova [-] unexpected indent (driver.py, line 171)

As you can see, there is a TAB at the beginning of line 171.
