    Many Thanks Matei Cezar!

    What a perfect procedure to deploy OpenStack!!! i was trying since last few days as per RDO official documentation and every time my installation was failing due to one or the other reason, unable to start nova scheduler, Nova table not found in DB, unable to download something and what not.

    Just completed installing Queens release on CentOS 7.5 (1804) without a single glitch. Thanks again.

    Keep Rocking!

    While generating your answer file for packstack you have used single quotations instead of backticks.

    > packstack –gen-answer-file=`date +”%d.%m.%y”`.conf
