Open Stack

Hi James,


I'm pretty new to OpenStack, but I'm working on setting up exactly the same
thing right now.  I'm having some other issues a little before where you
are with my stonith device so I don't really have any insight on your exact
problem.  If I get mine to work I'll share what I did.

However, my first thought is SELinux.  If you've checked file permissions
and they look ok, is SELinux Enforcing?  If so, you might try to
temporarily set it to permissive.  If that fixes the problem then check
audit logs for what you're missing.  It could be a missing context.

Just my two cents.
