Description of problem: If you disable nova compute in packstack's answer file you get an this error: # packstack -d --answer-file=testans.txt Welcome to Installer setup utility Installing: ERROR : 'CONFIG_NOVA_COMPUTE_HOSTS' How reproducible: Just set CONFIG_NOVA_INSTALL=n in the answer file Steps to Reproduce: 1. packstack --gent-answer-file=ans.txt 2. edit answer file and set CONFIG_NOVA_INSTALL to 'n' 3. run packstack -d --answer-file=ans.txt Actual results: Welcome to Installer setup utility Installing: ERROR : 'CONFIG_NOVA_COMPUTE_HOSTS' Expected results: Normal packstack output Additional info: It seems like the neutron plugin does not check if nova is disabled.
While solving this bug i found that the glance plugin also has this problem.
