Comment 1 Lukas Bezdicka 2014-06-02 15:16:58 UTC

I can see that we don't specify conductor_workers which means it is by default set to fact $::processorcount which in short does 'grep processor /proc/cpuinfo | wc -l' which should be count of real cores on machine. Could I see info about machine where you hit this issue? Probably output of facter and content of /proc/cpuinfo and number of workers set in nova.conf?

Comment 2 Stephen Gordon 2014-06-02 15:56:58 UTC

Moving the NEEDINFO to Ami, he actually raised this bug against RDO - this is the RHELOSP clone I created because I thought it was important enough to track against product requirements as well.
