Re: Command to find out list of compute nodes
I ran nova-compute in the foreground, and I don't see any error messages,
only DEBUG/INFO/AUDIT messages. I also don't see nova-compute exiting
when run in foreground. I am currently sifting through the log messages
spit out by nova-compute. I have also copied the log messages onto
pastebin - http://pastebin.com/8tdZr2mr
Thank you very much for helping out.
Regards,
Ahmed.
