nova-compute crashes immediately after starting on one of my workers on Ubuntu 13.10:

2013-11-22 13:01:24.383 18260 TRACE nova.openstack.common.threadgroup ProcessExecutionError: Unexpected error while running command.

This problem only occurs when running nova-compute from the upstart script. When running "nova-compute" as root, I don't have this problem and nova-compute just keeps running. I've deleted all bridges manually, but the problem persists.

I ended up deleting all files in /etc/nova and /etc/neutron, then purged and re-installed nova-compute and neutron. After applying my puppet configuration, nova-compute doesn't complain about the existing bridges anymore.

Since you have re-installed, question is not valid anymore. May be some intermediate issue surfaced. Any way I have close the issue. Hope it is ok.
