i nova-compute 2011.2~bzr925-0ubuntu0ppa1~maverick1 OpenStack Compute - Nova - compute node OS: Ubuntu maverick server

well, I try to use deploment tool with truck instead of release

there comes some error

2011-03-31 12:07:08,691 - INFO - Execute shell command: ssh -o StrictHostKeyChecking=no -t nii@ubuntu3.tw.megatrends.com 'sudo -u root sh -c "service nova-compute status"' 2011-03-31 12:07:08,691 - DEBUG - The output of the shell command is from here: 2011-03-31 12:07:08,807 - DEBUG - nova-compute stop/waiting 2011-03-31 12:07:08,807 - DEBUG - Connection to http://ubuntu3.tw.megatrends.com closed. 2011-03-31 12:07:08,807 - DEBUG - The output of the shell command is to here. 2011-03-31 12:07:08,808 - DEBUG - 2011-03-31 12:07:08,808 - DEBUG - 2011-03-31 12:07:08,808 - ERROR - Error occured when staring the service(nova-compute).

so I trun to ubuntu3 host and check nova-compute.log
