G'day all I located the cause (thanks to Vish's pointer in the right direction, that this was api paste related).
Turns out that the single line: /services/Admin: ec2admin That was removed from the [composite:ec2] stanza within Nova's api- paste.ini file during commit 638ea66969 caused nova-api to not run per the initial bug report below. The fix was to simply remove the "/services/Admin: ec2admin" line and restart the nova-api service, voila - Nova is running again :-) I hope this information helps others.

I guess it is shipping its own?
