Open Stack

This is not very informative.

I'll give you a suggestion.

Open up the log file(tail -f /var/log/nova/nova-compute.log) . Then launch an instance. Send only the errors that show up during the launch.

Also I would like to see error in scheduler and nova-api .

thank you,
Ageeleshwar K

Subject: [Openstack] error while launching instance

Hi, all
   One day, it came to me that OpenStack is funny and maybe I would like to do something with it.First, I got one controller node and one compute node,then I followed the installation guides on the website. When I set up those necessary services, I began to launch instance through dashboard. After about three minutes when the "Launch" button was clicked, there came a error like this:
[cid:2ac87516$1$145f09a1434$Coremail$zhichengli$zju.edu.cn]

In compute node,there are some errors in the file /var/log/nova/nova-compute.log,some of which are:
WARNING nova.openstack.common.db.sqlalchemy.session. SQL connection failed. 10 attempts left.

ERROR oslo.messaging._drivers.common Returning exception Remote error:
ProcessExecutionError Unexpected error while running command.

Exit code:11

I googled that, nothing worked for me.Could you please show me where should I go?
