Installing on RHEL - Prerequisites
If you're installing on RHEL, you must have your system registered with RHD, Satellite server, or a Yum repository. I'ts also a good idea to run "yum update" prior to starting the install, since the OpenStack software evolves very fast.
Installing with multiple NICs
If you're installing on a system with multiple NICs, "packstack –allinone" may not configure services on the interface you intended. To be certain, run "packstack –gen-answer-file=file_name", and then edit the resulting answer file to ensure that it's using the interface you wanted. Then run "packstack –answer-file=file_name"
