sgordon commented on a discussion. @bv_arvind: As per my answers to your questions on ask.openstack.org, if you use the SRPM for nova (openstack-nova-2013.1.2-1.el6.src.rpm) as suggested by @pixelbeat above then you will get what you are after. From the output you pasted it looks like you rebuilt rdo-release-grizzly-3.src.rpm instead. --- Follow the link below to check it out: http://openstack.redhat.com/forum/discussion/comment/667#Comment_667 Have a great day!
