start nova-compute failure
Hi experts,
when I run the command(nova-manage service list), I get the below output
root@Userver2:~# nova-manage service list
2012-09-21 17:36:49 DEBUG nova.utils [req-db670af0-2d15-4607-a23d-72dd7d97cb0d None None] backend
I noticed that the nova-compute serice can not start. then I run the command (start nova-compute), and I get the following error in the /var/log/nova/nova-compute.log.
