This bit is completely missing from the install guide: nova user must be 
able to ssh to other nodes. There's no mention whether it must be every 
node to every node, controller to every compute node, or what.

RedHat (RDO) uses /sbin/nologin instead. So you can't 'su - nova' and 
genrate keys & test ssh without editing /etc/passwd. I expect nSALinux 
would complain if you do that -- if you didn't disable it first thing 
after install.

(Of course if you could 'su - nova' you'd be in the right home directory.)
