Open Stack

Hello Fellow OpenStackers,

I was working on a bug (https://bugzilla.redhat.com/show_bug.cgi?id=975014) involving the Nova resize functionality in the libvirt driver.  So, it turns out that the bug is caused by nova code trying to ssh directly into another compute node.  Since it was not authorized to do so, the command failed.

So, my question is this: should nova really be SSHing directly into a peer machine to create a directory?  Doesn't that kind of defeat the purpose of the centralized RPC mechanism?  However, if this is the intended functionality, should Packstack be smarter about setting up permissions (this was a packstack install) when there are two or more compute nodes listed?
 
Best Regards,
Solly Ross

P.S. Yes, I know that was more than one question :-P
