:~# nova-manage help
[Errno 2] No such file or directory: '/etc/nova/nova-compute.conf'
ERROR:: Unable to open flagfile: /etc/nova/nova-compute.conf

Hmm, this looks like a packaging issue. It looks like by default the nova.conf is importing a new flagfile for nova-compute. If nova-compute isn't installed that file won't exist. The error won't actually stop anything from working, but it is annoying to see it pop up

Not sure about the best solution here, should nova-common install an empty nova-compute.conf that can be overwritten by the nova-compute package selected? Should nova-compute append --flagfile=nova.compute.conf to nova.conf when it is installed? Should we find a way to supress the error message in nova?

Argh, I didn't realise there would be a warning if the file was missing.

Debian Policy forbids us from altering the contents of a conffile from
maintainer scripts, so we can't append to nova.conf when nova-compute
gets installed.

I suggest we either a --optional-flagfile that doesn't warn or perhaps
make it so that "--flagfile=@/some/path" silently ignores /some/path's

Why not just have nova-compute's init/upstart script run nova-compute with --flagfile=/etc/nova/nova-compute.conf and include nova.conf from there?

But it looks like --libvirt_type is needed in places other than just nova-compute?

Either way, something seems wrong. If you only need nova-compute.conf for the compute service, then my first suggestion should work. Otherwise, nova-compute.conf needs to always exist no?

As far as I can see, this was just a packaging issue and that has been resolved, so the nova bug can be closed out.
