I got error when I try to restart the nova-compute service on my compute node.

[root@mycompute ~]# service nova-compute restart
Stopping OpenStack Nova Compute Worker:                    [  OK  ]
Starting OpenStack Nova Compute Worker:                    [FAILED]

I check in the log file /var/log/nova/nova-compute.log but nothing is logged in that file.

Then I try to run the command with nova user.

[root@mycompute ~]# su -s/bin/bash nova
bash-4.1$ /usr/bin/nova-compute
Bus error (core dumped)

I got the log in /var/log/messages

Is there something in any other log file? /var/log/messages or similar maybe? –  SvW Nov 21 '12 at 4:37
    
@SvenW I added message log. –  Lafada Nov 21 '12 at 5:55
