I am having troubles booting an server.  It will start booting, perhaps for
several minutes, and then it will go into an error state.

​I have tried using the --debug switch to the nova command, and I see the
API calls go by.  They all have 200 status codes.

I have tried fgreping the ID in /var/log/*​ with the -r switch, and I see
lots of GETs with 200 status returns.  On one of the tests, I was
experimenting with using a network port, and I see that something is
deleting the network port, but this latest attempt didn't use a network
port.


What I am looking for is a pointer to a general troubleshooting process.
 If everybody who is having problems sends a message to a mailing list -
well, that doesn't scale very well.


Thank you


Jeff
